- * Debugging:
- * 	Use the 'lsusb' utility to dump the descriptors.
- *
- * 1999-09-07:  Alan Cox
- *		Parsing Audio descriptor patch
- * 1999-09-08:  Thomas Sailer
- *		Added OSS compatible data io functions; both parts of the
- *		driver remain to be glued together
- * 1999-09-10:  Thomas Sailer
- *		Beautified the driver. Added sample format conversions.
- *		Still not properly glued with the parsing code.
- *		The parsing code seems to have its problems btw,
- *		Since it parses all available configs but doesn't
- *		store which iface/altsetting belongs to which config.
- * 1999-09-20:  Thomas Sailer
- *		Threw out Alan's parsing code and implemented my own one.
- *		You cannot reasonnably linearly parse audio descriptors,
- *		especially the AudioClass descriptors have to be considered
- *		pointer lists. Mixer parsing untested, due to lack of device.
- *		First stab at synch pipe implementation, the Dallas USB DAC
- *		wants to use an Asynch out pipe. usb_audio_state now basically
- *		only contains lists of mixer and wave devices. We can therefore
- *		now have multiple mixer/wave devices per USB device.
- * 1999-10-28:  Thomas Sailer
- *		Converted to URB API. Fixed a taskstate/wakeup semantics mistake
- *		that made the driver consume all available CPU cycles.
- *		Now runs stable on UHCI-Acher/Fliegl/Sailer.
- * 1999-10-31:  Thomas Sailer
- *		Audio can now be unloaded if it is not in use by any mixer
- *		or dsp client (formerly you had to disconnect the audio devices
- *		from the USB port)
- *		Finally, about three months after ordering, my "Maxxtro SPK222"
- *		speakers arrived, isn't disdata a great mail order company 8-)
- *		Parse class specific endpoint descriptor of the audiostreaming
- *		interfaces and take the endpoint attributes from there.
- *		Unbelievably, the Philips USB DAC has a sampling rate range
- *		of over a decade, yet does not support the sampling rate control!
- *		No wonder it sounds so bad, has very audible sampling rate
- *		conversion distortion. Don't try to listen to it using
- *		decent headphones!
- *		"Let's make things better" -> but please Philips start with your
- *		own stuff!!!!
- * 1999-11-02:  Thomas Sailer
- *		It takes the Philips boxes several seconds to acquire synchronisation
- *		that means they won't play short sounds. Should probably maintain
- *		the ISO datastream even if there's nothing to play.
- *		Fix counting the total_bytes counter, RealPlayer G2 depends on it.
- * 1999-12-20:  Thomas Sailer
- *		Fix bad bug in conversion to per interface probing.
- *		disconnect was called multiple times for the audio device,
- *		leading to a premature freeing of the audio structures
- * 2000-05-13:  Thomas Sailer
- *		I don't remember who changed the find_format routine,
- *              but the change was completely broken for the Dallas
- *              chip. Anyway taking sampling rate into account in find_format
- *              is bad and should not be done unless there are devices with
- *              completely broken audio descriptors. Unless someone shows
- *              me such a descriptor, I will not allow find_format to
- *              take the sampling rate into account.
- *              Also, the former find_format made:
- *              - mpg123 play mono instead of stereo
- *              - sox completely fail for wav's with sample rates < 44.1kHz
- *                  for the Dallas chip.
- *              Also fix a rather long standing problem with applications that
- *              use "small" writes producing no sound at all.
- * 2000-05-15:  Thomas Sailer
- *		My fears came true, the Philips camera indeed has pretty stupid
- *              audio descriptors.
- * 2000-05-17:  Thomas Sailer
- *		Nemsoft spotted my stupid last minute change, thanks
- * 2000-05-19:  Thomas Sailer
- *		Fixed FEATURE_UNIT thinkos found thanks to the KC Technology
- *              Xtend device. Basically the driver treated FEATURE_UNIT's sourced
- *              by mono terminals as stereo.
- * 2000-05-20:  Thomas Sailer
- *		SELECTOR support (and thus selecting record channels from the mixer).
- *              Somewhat peculiar due to OSS interface limitations. Only works
- *              for channels where a "slider" is already in front of it (i.e.
- *              a MIXER unit or a FEATURE unit with volume capability).
- * 2000-11-26:  Thomas Sailer
- *              Workaround for Dallas DS4201. The DS4201 uses PCM8 as format tag for
- *              its 8 bit modes, but expects signed data (and should therefore have used PCM).
- * 2001-03-10:  Thomas Sailer
- *              provide abs function, prevent picking up a bogus kernel macro
- *              for abs. Bug report by Andrew Morton <andrewm@uow.edu.au>
- * 2001-06-16:  Bryce Nesbitt <bryce@obviously.com>
- *              Fix SNDCTL_DSP_STEREO API violation
- * 2003-04-08:	Oliver Neukum (oliver@neukum.name):
- *		Setting a configuration is done by usbcore and must not be overridden
- * 2004-02-27:  Workaround for broken synch descriptors
- * 2004-03-07:	Alan Stern <stern@rowland.harvard.edu>
- *		Add usb_ifnum_to_if() and usb_altnum_to_altsetting() support.
- *		Use the in-memory descriptors instead of reading them from the device.

-/*
- * Strategy:
- *
- * Alan Cox and Thomas Sailer are starting to dig at opposite ends and
- * are hoping to meet in the middle, just like tunnel diggers :)
- * Alan tackles the descriptor parsing, Thomas the actual data IO and the
- * OSS compatible interface.
- *
- * Data IO implementation issues
- *
- * A mmap'able ring buffer per direction is implemented, because
- * almost every OSS app expects it. It is however impractical to
- * transmit/receive USB data directly into and out of the ring buffer,
- * due to alignment and synchronisation issues. Instead, the ring buffer
- * feeds a constant time delay line that handles the USB issues.
- *
- * Now we first try to find an alternate setting that exactly matches
- * the sample format requested by the user. If we find one, we do not
- * need to perform any sample rate conversions. If there is no matching
- * altsetting, we choose the closest one and perform sample format
- * conversions. We never do sample rate conversion; these are too
- * expensive to be performed in the kernel.
- *
- * Current status: no known HCD-specific issues.
- *
- * Generally: Due to the brokenness of the Audio Class spec
- * it seems generally impossible to write a generic Audio Class driver,
- * so a reasonable driver should implement the features that are actually
- * used.
- *
- * Parsing implementation issues
- *
- * One cannot reasonably parse the AudioClass descriptors linearly.
- * Therefore the current implementation features routines to look
- * for a specific descriptor in the descriptor list.
- *
- * How does the parsing work? First, all interfaces are searched
- * for an AudioControl class interface. If found, the config descriptor
- * that belongs to the current configuration is searched and
- * the HEADER descriptor is found. It contains a list of
- * all AudioStreaming and MIDIStreaming devices. This list is then walked,
- * and all AudioStreaming interfaces are classified into input and output
- * interfaces (according to the endpoint0 direction in altsetting1) (MIDIStreaming
- * is currently not supported). The input & output list is then used
- * to group inputs and outputs together and issued pairwise to the
- * AudioStreaming class parser. Finally, all OUTPUT_TERMINAL descriptors
- * are walked and issued to the mixer construction routine.
- *
- * The AudioStreaming parser simply enumerates all altsettings belonging
- * to the specified interface. It looks for AS_GENERAL and FORMAT_TYPE
- * class specific descriptors to extract the sample format/sample rate
- * data. Only sample format types PCM and PCM8 are supported right now, and
- * only FORMAT_TYPE_I is handled. The isochronous data endpoint needs to
- * be the first endpoint of the interface, and the optional synchronisation
- * isochronous endpoint the second one.
- *
- * Mixer construction works as follows: The various TERMINAL and UNIT
- * descriptors span a tree from the root (OUTPUT_TERMINAL) through the
- * intermediate nodes (UNITs) to the leaves (INPUT_TERMINAL). We walk
- * that tree in a depth first manner. FEATURE_UNITs may contribute volume,
- * bass and treble sliders to the mixer, MIXER_UNITs volume sliders.
- * The terminal type encoded in the INPUT_TERMINALs feeds a heuristic
- * to determine "meaningful" OSS slider numbers, however we will see
- * how well this works in practice. Other features are not used at the
- * moment, they seem less often used. Also, it seems difficult at least
- * to construct recording source switches from SELECTOR_UNITs, but
- * since there are not many USB ADC's available, we leave that for later.

-/* A driver for the D-Link DSB-R100 USB radio.  The R100 plugs
- into both the USB and an analog audio input, so this thing
- only deals with initialisation and frequency setting, the
- audio data has to be handled by a sound driver.
-
- Major issue: I can't find out where the device reports the signal
- strength, and indeed the windows software appearantly just looks
- at the stereo indicator as well.  So, scanning will only find
- stereo stations.  Sad, but I can't help it.
-
- Also, the windows program sends oodles of messages over to the
- device, and I couldn't figure out their meaning.  My suspicion
- is that they don't have any:-)

-
-The main webpage for the Philips driver is at the address above. It contains
-a lot of extra information, a FAQ, and the binary plugin 'PWCX'. This plugin
-contains decompression routines that allow you to use higher image sizes and
-framerates; in addition the webcam uses less bandwidth on the USB bus (handy
-if you want to run more than 1 camera simultaneously). These routines fall
-under a NDA, and may therefor not be distributed as source; however, its use
-is completely optional.
-
-You can build this code either into your kernel, or as a module. I recommend
-the latter, since it makes troubleshooting a lot easier. The built-in
-microphone is supported through the USB Audio class.
-
-When you load the module you can set some default settings for the
-camera; some programs depend on a particular image-size or -format and
-don't know how to set it properly in the driver. The options are:
-
-size
-   Can be one of 'sqcif', 'qsif', 'qcif', 'sif', 'cif' or
-   'vga', for an image size of resp. 128x96, 160x120, 176x144,
-   320x240, 352x288 and 640x480 (of course, only for those cameras that 
-   support these resolutions).
-
-fps
-   Specifies the desired framerate. Is an integer in the range of 4-30.
-
-fbufs
-   This paramter specifies the number of internal buffers to use for storing 
-   frames from the cam. This will help if the process that reads images from 
-   the cam is a bit slow or momentarely busy. However, on slow machines it 
-   only introduces lag, so choose carefully. The default is 3, which is 
-   reasonable. You can set it between 2 and 5.
-
-mbufs
-   This is an integer between 1 and 10. It will tell the module the number of
-   buffers to reserve for mmap(), VIDIOCCGMBUF, VIDIOCMCAPTURE and friends.
-   The default is 2, which is adequate for most applications (double
-   buffering).
-      
-   Should you experience a lot of 'Dumping frame...' messages during
-   grabbing with a tool that uses mmap(), you might want to increase if. 
-   However, it doesn't really buffer images, it just gives you a bit more
-   slack when your program is behind. But you need a multi-threaded or
-   forked program to really take advantage of these buffers.
-
-   The absolute maximum is 10, but don't set it too high!  Every buffer takes
-   up 460 KB of RAM, so unless you have a lot of memory setting this to
-   something more than 4 is an absolute waste.  This memory is only
-   allocated during open(), so nothing is wasted when the camera is not in
-   use.
-
-power_save
-   When power_save is enabled (set to 1), the module will try to shut down
-   the cam on close() and re-activate on open(). This will save power and
-   turn off the LED. Not all cameras support this though (the 645 and 646
-   don't have power saving at all), and some models don't work either (they
-   will shut down, but never wake up). Consider this experimental. By
-   default this option is disabled.
-
-compression (only useful with the plugin)
-   With this option you can control the compression factor that the camera
-   uses to squeeze the image through the USB bus. You can set the 
-   parameter between 0 and 3:
-     0 = prefer uncompressed images; if the requested mode is not available
-         in an uncompressed format, the driver will silently switch to low
-         compression.
-     1 = low compression.
-     2 = medium compression.
-     3 = high compression.
-      
-   High compression takes less bandwidth of course, but it could also
-   introduce some unwanted artefacts. The default is 2, medium compression.
-   See the FAQ on the website for an overview of which modes require
-   compression.
-
-   The compression parameter does not apply to the 645 and 646 cameras
-   and OEM models derived from those (only a few). Most cams honour this
-   parameter.
-
-leds
-   This settings takes 2 integers, that define the on/off time for the LED
-   (in milliseconds). One of the interesting things that you can do with
-   this is let the LED blink while the camera is in use. This:
-
-     leds=500,500
-      
-   will blink the LED once every second. But with:
-
-     leds=0,0
-
-   the LED never goes on, making it suitable for silent surveillance.
-
-   By default the camera's LED is on solid while in use, and turned off
-   when the camera is not used anymore.
-
-   This parameter works only with the ToUCam range of cameras (720, 730, 740,
-   750) and OEMs. For other cameras this command is silently ignored, and 
-   the LED cannot be controlled.
-
-   Finally: this parameters does not take effect UNTIL the first time you
-   open the camera device. Until then, the LED remains on.
-
-dev_hint
-   A long standing problem with USB devices is their dynamic nature: you
-   never know what device a camera gets assigned; it depends on module load
-   order, the hub configuration, the order in which devices are plugged in,
-   and the phase of the moon (i.e. it can be random). With this option you
-   can give the driver a hint as to what video device node (/dev/videoX) it
-   should use with a specific camera. This is also handy if you have two
-   cameras of the same model.
-
-   A camera is specified by its type (the number from the camera model,
-   like PCA645, PCVC750VC, etc) and optionally the serial number (visible
-   in /proc/bus/usb/devices). A hint consists of a string with the following
-   format:
-
-      [type[.serialnumber]:]node
-      
-   The square brackets mean that both the type and the serialnumber are
-   optional, but a serialnumber cannot be specified without a type (which
-   would be rather pointless). The serialnumber is separated from the type
-   by a '.'; the node number by a ':'.
-   
-   This somewhat cryptic syntax is best explained by a few examples:
-
-     dev_hint=3,5              The first detected cam gets assigned
-                               /dev/video3, the second /dev/video5. Any
-                               other cameras will get the first free 
-                               available slot (see below).
-
-     dev_hint=645:1,680:2      The PCA645 camera will get /dev/video1,
-                               and a PCVC680 /dev/video2.
-                               
-     dev_hint=645.0123:3,645.4567:0	The PCA645 camera with serialnumber 
-                                        0123 goes to /dev/video3, the same
-                                        camera model with the 4567 serial
-                                        gets /dev/video0.
-
-     dev_hint=750:1,4,5,6       The PCVC750 camera will get /dev/video1, the 
-                                next 3 Philips cams will use /dev/video4 
-                                through /dev/video6.
-
-   Some points worth knowing:
-   - Serialnumbers are case sensitive and must be written full, including 
-     leading zeroes (it's treated as a string).
-   - If a device node is already occupied, registration will fail and 
-     the webcam is not available.
-   - You can have up to 64 video devices; be sure to make enough device
-     nodes in /dev if you want to spread the numbers (this does not apply
-     to devfs). After /dev/video9 comes /dev/video10 (not /dev/videoA).
-   - If a camera does not match any dev_hint, it will simply get assigned
-     the first available device node, just as it used to be.
-
-trace
-   In order to better detect problems, it is now possible to turn on a
-   'trace' of some of the calls the module makes; it logs all items in your
-   kernel log at debug level.
-
-   The trace variable is a bitmask; each bit represents a certain feature.
-   If you want to trace something, look up the bit value(s) in the table 
-   below, add the values together and supply that to the trace variable.
-
-   Value  Value   Description					   Default
-   (dec)  (hex)
-       1    0x1   Module initialization; this will log messages       On
-                  while loading and unloading the module
-
-       2    0x2   probe() and disconnect() traces                     On
-
-       4    0x4   Trace open() and close() calls                      Off
-
-       8    0x8   read(), mmap() and associated ioctl() calls         Off
-
-      16   0x10   Memory allocation of buffers, etc.                  Off
-
-      32   0x20   Showing underflow, overflow and Dumping frame       On
-                  messages
-
-      64   0x40   Show viewport and image sizes                       Off
-
-     128   0x80   PWCX debugging                                      Off
-
-   For example, to trace the open() & read() fuctions, sum 8 + 4 = 12,
-   so you would supply trace=12 during insmod or modprobe. If
-   you want to turn the initialization and probing tracing off, set trace=0.
-   The default value for trace is 35 (0x23).
-
-
-
-Example:
-     
-     # modprobe pwc size=cif fps=15 power_save=1
-
-The fbufs, mbufs and trace parameters are global and apply to all connected
-cameras. Each camera has its own set of buffers.
-
-size and fps only specify defaults when you open() the device; this is to
-accommodate some tools that don't set the size. You can change these
-settings after open() with the Video4Linux ioctl() calls. The default of
-defaults is QCIF size at 10 fps.
-
-The compression parameter is semiglobal; it sets the initial compression
-preference for all camera's, but this parameter can be set per camera with
-the VIDIOCPWCSCQUAL ioctl() call.
-
-All parameters are optional.

-/* Okay, this is some magic that I worked out and the reasoning behind it...
-
-   The biggest problem with any USB device is of course: "what to do 
-   when the user unplugs the device while it is in use by an application?"
-   We have several options:
-   1) Curse them with the 7 plagues when they do (requires divine intervention)
-   2) Tell them not to (won't work: they'll do it anyway)
-   3) Oops the kernel (this will have a negative effect on a user's uptime)
-   4) Do something sensible.
-   
-   Of course, we go for option 4.
-
-   It happens that this device will be linked to two times, once from
-   usb_device and once from the video_device in their respective 'private'
-   pointers. This is done when the device is probed() and all initialization
-   succeeded. The pwc_device struct links back to both structures.
-
-   When a device is unplugged while in use it will be removed from the 
-   list of known USB devices; I also de-register it as a V4L device, but 
-   unfortunately I can't free the memory since the struct is still in use
-   by the file descriptor. This free-ing is then deferend until the first
-   opportunity. Crude, but it works.
-   
-   A small 'advantage' is that if a user unplugs the cam and plugs it back
-   in, it should get assigned the same video device minor, but unfortunately
-   it's non-trivial to re-link the cam back to the video device... (that 
-   would surely be magic! :))

-/* The frame & image buffer mess. 
-
-   Yes, this is a mess. Well, it used to be simple, but alas...  In this
-   module, 3 buffers schemes are used to get the data from the USB bus to
-   the user program. The first scheme involves the ISO buffers (called thus
-   since they transport ISO data from the USB controller), and not really
-   interesting. Suffices to say the data from this buffer is quickly 
-   gathered in an interrupt handler (pwc_isoc_handler) and placed into the
-   frame buffer.
-
-   The frame buffer is the second scheme, and is the central element here.
-   It collects the data from a single frame from the camera (hence, the
-   name). Frames are delimited by the USB camera with a short USB packet,
-   so that's easy to detect. The frame buffers form a list that is filled
-   by the camera+USB controller and drained by the user process through
-   either read() or mmap().
-
-   The image buffer is the third scheme, in which frames are decompressed
-   and converted into planar format. For mmap() there is more than
-   one image buffer available.
-
-   The frame buffers provide the image buffering. In case the user process
-   is a bit slow, this introduces lag and some undesired side-effects.
-   The problem arises when the frame buffer is full. I used to drop the last
-   frame, which makes the data in the queue stale very quickly. But dropping
-   the frame at the head of the queue proved to be a litte bit more difficult.
-   I tried a circular linked scheme, but this introduced more problems than
-   it solved.
-
-   Because filling and draining are completely asynchronous processes, this
-   requires some fiddling with pointers and mutexes.
-
-   Eventually, I came up with a system with 2 lists: an 'empty' frame list
-   and a 'full' frame list:
-     * Initially, all frame buffers but one are on the 'empty' list; the one
-       remaining buffer is our initial fill frame.
-     * If a frame is needed for filling, we try to take it from the 'empty' 
-       list, unless that list is empty, in which case we take the buffer at 
-       the head of the 'full' list.
-     * When our fill buffer has been filled, it is appended to the 'full'
-       list.
-     * If a frame is needed by read() or mmap(), it is taken from the head of
-       the 'full' list, handled, and then appended to the 'empty' list. If no
-       buffer is present on the 'full' list, we wait.
-   The advantage is that the buffer that is currently being decompressed/
-   converted, is on neither list, and thus not in our way (any other scheme
-   I tried had the problem of old data lingering in the queue).
-
-   Whatever strategy you choose, it always remains a tradeoff: with more
-   frame buffers the chances of a missed frame are reduced. On the other
-   hand, on slower machines it introduces lag because the queue will
-   always be full.

-                the need, second there's no mechanism of alerting the
-                2nd/3rd/... process of events like changing image size.
-                And I don't see the point of blocking that for the
-                2nd/3rd/... process.
-                In multi-threaded environments reading parallel from any
-                device is tricky anyhow.

-   OVERVIEW.
-   This is a small interface that allows you to add support for any CCD/CMOS
-   image sensors connected to the SN9C10X bridges. The entire API is documented
-   below. In the most general case, to support a sensor there are three steps
-   you have to follow:
-   1) define the main "sn9c102_sensor" structure by setting the basic fields;
-   2) write a probing function to be called by the core module when the USB
-      camera is recognized, then add both the USB ids and the name of that
-      function to the two corresponding tables SENSOR_TABLE and ID_TABLE (see
-      below);
-   3) implement the methods that you want/need (and fill the rest of the main
-      structure accordingly).
-   "sn9c102_pas106b.c" is an example of all this stuff. Remember that you do
-   NOT need to touch the source code of the core module for the things to work
-   properly, unless you find bugs or flaws in it. Finally, do not forget to
-   read the V4L2 API for completeness.

-/*****************************************************************************/

-/*
-   Probing functions: on success, you must attach the sensor to the camera
-   by calling sn9c102_attach_sensor() provided below.
-   To enable the I2C communication, you might need to perform a really basic
-   initialization of the SN9C10X chip by using the write function declared 
-   ahead.
-   Functions must return 0 on success, the appropriate error otherwise.

-	   It is not always true that the largest achievable active window can
-	   cover the whole array of pixels. The V4L2 API defines another
-	   area called "source rectangle", which, in turn, is a subrectangle of
-	   the active window. The SN9C10X chip is always programmed to read the
-	   source rectangle.
-	   The bounds of both the active window and the source rectangle are
-	   specified in the cropcap substructures 'bounds' and 'defrect'.
-	   By default, the source rectangle should cover the largest possible
-	   area. Again, it is not always true that the largest source rectangle
-	   can cover the entire active window, although it is a rare case for 
-	   the hardware we have. The bounds of the source rectangle _must_ be
-	   multiple of 16 and must use the same coordinate system as indicated
-	   before; their centers shall align initially.
-	   If necessary, the sensor chip must be initialized during init() to
-	   set the bounds of the active sensor window; however, by default, it
-	   usually covers the largest achievable area (maxwidth x maxheight)
-	   of pixels, so no particular initialization is needed, if you have
-	   defined the correct default bounds in the structures.
-	   See the V4L2 API for further details.
-	   NOTE: once you have defined the bounds of the active window
-	         (struct cropcap.bounds) you must not change them.anymore.

- *  STV0680 USB Camera Driver, by Kevin Sisson (kjsisson@bellsouth.net)
- *  
- * Thanks to STMicroelectronics for information on the usb commands, and 
- * to Steve Miller at STM for his help and encouragement while I was 
- * writing this driver.
- *
- * This driver is based heavily on the 
- * Endpoints (formerly known as AOX) se401 USB Camera Driver
- * Copyright (c) 2000 Jeroen B. Vreeken (pe1rxq@amsat.org)
- *
- * Still somewhat based on the Linux ov511 driver.

- * Free Software Foundation; either version 2 of the License, or (at your
- * option) any later version.

- * along with this program; if not, write to the Free Software Foundation,
- * Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
- *
- * History: 
- * ver 0.1 October, 2001. Initial attempt. 
- *
- * ver 0.2 November, 2001. Fixed asbility to resize, added brightness
- *                         function, made more stable (?)
- *
- * ver 0.21 Nov, 2001.     Added gamma correction and white balance, 
- *                         due to Alexander Schwartz. Still trying to 
- *                         improve stablility. Moved stuff into stv680.h
- *
- * ver 0.22 Nov, 2001.	   Added sharpen function (by Michael Sweet, 
- *                         mike@easysw.com) from GIMP, also used in pencam. 
- *                         Simple, fast, good integer math routine.
- *
- * ver 0.23 Dec, 2001 (gkh)
- * 			   Took out sharpen function, ran code through
- * 			   Lindent, and did other minor tweaks to get
- * 			   things to work properly with 2.5.1
- *
- * ver 0.24 Jan, 2002 (kjs) 
- *                         Fixed the problem with webcam crashing after
- *                         two pictures. Changed the way pic is halved to 
- *                         improve quality. Got rid of green line around 
- *                         frame. Fix brightness reset when changing size 
- *                         bug. Adjusted gamma filters slightly.
- *
- * ver 0.25 Jan, 2002 (kjs)
- *			   Fixed a bug in which the driver sometimes attempted
- *			   to set to a non-supported size. This allowed
- *			   gnomemeeting to work.
- *			   Fixed proc entry removal bug.
