+ * the suspend method for @udev itself.  If an error occurs at any stage,
+ * all the interfaces which were suspended are resumed so that they remain
+ * in the same state as the device.
+ *
+ * If an autosuspend is in progress (@udev->auto_pm is set), the routine
+ * checks first to make sure that neither the device itself or any of its
+ * active interfaces is in use (pm_usage_cnt is greater than 0).  If they
+ * are, the autosuspend fails.
+ *
+ * If the suspend succeeds, the routine recursively queues an autosuspend
+ * request for @udev's parent device, thereby propagating the change up
+ * the device tree.  If all of the parent's children are now suspended,
+ * the parent will autosuspend in turn.
+ *
+ * The suspend method calls are subject to mutual exclusion under control
+ * of @udev's pm_mutex.  Many of these calls are also under the protection
+ * of @udev's device lock (including all requests originating outside the
+ * USB subsystem), but autosuspend requests generated by a child device or
+ * interface driver may not be.  Usbcore will insure that the method calls
+ * do not arrive during bind, unbind, or reset operations.  However, drivers
+ * must be prepared to handle suspend calls arriving at unpredictable times.
+ * The only way to block such calls is to do an autoresume (preventing
+ * autosuspends) while holding @udev's device lock (preventing outside
+ * suspends).
+ *
+ * The caller must hold @udev->pm_mutex.

+	  The U132 adapter is a USB to CardBus adapter specifically designed
+	  for PC cards that contain an OHCI host controller. Typical PC cards
+	  are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
+	  adapter will *NOT* work with PC cards that do not contain an OHCI
+	  controller.
+
+	  For those PC cards that contain multiple OHCI controllers only ther
+	  first one is used.
+
+	  The driver consists of two modules, the "ftdi-elan" module is a
+	  USB client driver that interfaces to the FTDI chip within ELAN's
+	  USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
+	  controller driver that talks to the OHCI controller within the
+	  CardBus cards that are inserted in the U132 adapter.
+
+	  This driver has been tested with a CardBus OHCI USB adapter, and
+	  worked with a USB PEN Drive inserted into the first USB port of
+	  the PCCARD. A rather pointless thing to do, but useful for testing.
+
+	  It is safe to say M here.

+*
+* This program is free software;you can redistribute it and/or

+* published by the Free Software Foundation, version 2.
+*
+*
+* This driver was written by Tony Olech(tony.olech@elandigitalsystems.com)
+* based on various USB host drivers in the 2.6.15 linux kernel
+* with constant reference to the 3rd Edition of Linux Device Drivers
+* published by O'Reilly
+*
+* The U132 adapter is a USB to CardBus adapter specifically designed
+* for PC cards that contain an OHCI host controller. Typical PC cards
+* are the Orange Mobile 3G Option GlobeTrotter Fusion card.
+*
+* The U132 adapter will *NOT *work with PC cards that do not contain
+* an OHCI controller. A simple way to test whether a PC card has an
+* OHCI controller as an interface is to insert the PC card directly
+* into a laptop(or desktop) with a CardBus slot and if "lspci" shows
+* a new USB controller and "lsusb -v" shows a new OHCI Host Controller
+* then there is a good chance that the U132 adapter will support the
+* PC card.(you also need the specific client driver for the PC card)
+*
+* Please inform the Author and Maintainer about any PC cards that
+* contain OHCI Host Controller and work when directly connected to
+* an embedded CardBus slot but do not work when they are connected
+* via an ELAN U132 adapter.

+	  module which is a USB host controller driver that talks to the OHCI
+	  controller within CardBus card that are inserted in the U132 adapter.
+
+	  This driver has been tested with a CardBus OHCI USB adapter, and
+	  worked with a USB PEN Drive inserted into the first USB port of

+*
+*
+* This driver was written by Tony Olech(tony.olech@elandigitalsystems.com)
+* based on various USB client drivers in the 2.6.15 linux kernel
+* with constant reference to the 3rd Edition of Linux Device Drivers
+* published by O'Reilly
+*
+* The U132 adapter is a USB to CardBus adapter specifically designed
+* for PC cards that contain an OHCI host controller. Typical PC cards
+* are the Orange Mobile 3G Option GlobeTrotter Fusion card.
+*
+* The U132 adapter will *NOT *work with PC cards that do not contain
+* an OHCI controller. A simple way to test whether a PC card has an
+* OHCI controller as an interface is to insert the PC card directly
+* into a laptop(or desktop) with a CardBus slot and if "lspci" shows
+* a new USB controller and "lsusb -v" shows a new OHCI Host Controller
+* then there is a good chance that the U132 adapter will support the
+* PC card.(you also need the specific client driver for the PC card)
+*
+* Please inform the Author and Maintainer about any PC cards that
+* contain OHCI Host Controller and work when directly connected to
+* an embedded CardBus slot but do not work when they are connected
+* via an ELAN U132 adapter.

+/*
+* Common Header File for the Elan Digital Systems U132 adapter
+* this file should be included by both the "ftdi-u132" and
+* the "u132-hcd" modules.
+*
+* Copyright(C) 2006 Elan Digital Systems Limited
+*(http://www.elandigitalsystems.com)
+*
+* Author and Maintainer - Tony Olech - Elan Digital Systems
+*(tony.olech@elandigitalsystems.com)
+*
+* This program is free software;you can redistribute it and/or
+* modify it under the terms of the GNU General Public License as
+* published by the Free Software Foundation, version 2.
+*
+*
+* The driver was written by Tony Olech(tony.olech@elandigitalsystems.com)
+* based on various USB client drivers in the 2.6.15 linux kernel
+* with constant reference to the 3rd Edition of Linux Device Drivers
+* published by O'Reilly
+*
+* The U132 adapter is a USB to CardBus adapter specifically designed
+* for PC cards that contain an OHCI host controller. Typical PC cards
+* are the Orange Mobile 3G Option GlobeTrotter Fusion card.
+*
+* The U132 adapter will *NOT *work with PC cards that do not contain
+* an OHCI controller. A simple way to test whether a PC card has an
+* OHCI controller as an interface is to insert the PC card directly
+* into a laptop(or desktop) with a CardBus slot and if "lspci" shows
+* a new USB controller and "lsusb -v" shows a new OHCI Host Controller
+* then there is a good chance that the U132 adapter will support the
+* PC card.(you also need the specific client driver for the PC card)
+*
+* Please inform the Author and Maintainer about any PC cards that
+* contain OHCI Host Controller and work when directly connected to
+* an embedded CardBus slot but do not work when they are connected
+* via an ELAN U132 adapter.
+*
+* The driver consists of two modules, the "ftdi-u132" module is
+* a USB client driver that interfaces to the FTDI chip within
+* the U132 adapter manufactured by Elan Digital Systems, and the
+* "u132-hcd" module is a USB host controller driver that talks
+* to the OHCI controller within CardBus card that are inserted
+* in the U132 adapter.
+*
+* The "ftdi-u132" module should be loaded automatically by the
+* hot plug system when the U132 adapter is plugged in. The module
+* initialises the adapter which mostly consists of synchronising
+* the FTDI chip, before continuously polling the adapter to detect
+* PC card insertions. As soon as a PC card containing a recognised
+* OHCI controller is seen the "ftdi-u132" module explicitly requests
+* the kernel to load the "u132-hcd" module.
+*
+* The "ftdi-u132" module provides the interface to the inserted
+* PC card and the "u132-hcd" module uses the API to send and recieve
+* data. The API features call-backs, so that part of the "u132-hcd"
+* module code will run in the context of one of the kernel threads
+* of the "ftdi-u132" module.

+ *
+ * The device works as an standard CDC device, it has 2 interfaces, the first
+ * one is for firmware access and the second is the serial one.
+ * The protocol is very simply, there are two posibilities reading or writing.
+ * When writting the first urb must have a Header that starts with 0x20 0x29 the
+ * next two bytes must say how much data will be sended.
+ * When reading the process is almost equal except that the header starts with
+ * 0x00 0x20.
+ *
+ * The device simply need some stuff to understand data comming from the usb
+ * buffer: The First and Second byte is used for a Header, the Third and Fourth
+ * tells the  device the amount of information the package holds.
+ * Packages are 60 bytes long Header Stuff.
+ * When writting to the device the first two bytes of the header are 0x20 0x29
+ * When reading the bytes are 0x00 0x20, or 0x00 0x10, there is an strange
+ * situation, when too much data arrives to the device because it sends the data
+ * but with out the header. I will use a simply hack to override this situation,
+ * if there is data coming that does not contain any header, then that is data
+ * that must go directly to the tty, as there is no documentation about if there
+ * is any other control code, I will simply check for the first
+ * one.
+ *
+ * The driver registers himself with the USB-serial core and the USB Core. I had
+ * to implement a probe function agains USB-serial, because other way, the
+ * driver was attaching himself to both interfaces. I have tryed with different
+ * configurations of usb_serial_driver with out exit, only the probe function
+ * could handle this correctly.
+ *
+ * I have taken some info from a Greg Kroah-Hartman article:
+ * http://www.linuxjournal.com/article/6573
+ * And from Linux Device Driver Kit CD, which is a great work, the authors taken
+ * the work to recompile lots of information an knowladge in drivers development
+ * and made it all avaible inside a cd.
