2010-02-26V4L/DVB (13925): gspca - main: Change the check of the USB video interface.Jean-Francois Moine
Some webcams have many interfaces with the same interface class, so the previous interface check did not work. The new code checks if the interface number is zero or the only one. Signed-off-by: Jean-Francois Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-02-26V4L/DVB (13897): gspca - main: Check the interface class at probe time.Jean-Francois Moine
The USB video interface was checked as having the number zero, but some webcams have other values. The test is now done on the interface class which may be either 255 (vendor spec) or 0 (class per interface).

2009-12-05V4L/DVB (13184): gspca: Don't forget to resubmit URB's in case of an errorHans de Goede
The gscpa core was not resubmitting URB's when the URB status was an error, this means we will loose URB's (potentially all stopping the stream) in case of sporadic USB issues. I've seen this with an Aiptek stv0680 based PenCam connected through an USB 2.0 hub. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-12-05V4L/DVB (13178): gspca: Add support for Winbond W9967CF and W9968CF camera'sHans de Goede
This patch adds support to gspca for the Winbond W9967CF and W9968CF camera's. This is mostly a port of the existing v4l1 driver to gspca (making it v4l2). But this also features fixes to the bitbanging i2c code (send a nack not an ack after reading the last byte of a transfer), which gets rid of the weird errors which were being seen there, and of the smbus_refresh() hack to get around these errors. Also the vstart settings have been tweaked to work with different frequency filter settings.

2009-03-30V4L/DVB (11263): gspca: Stop setting buffer type, and avoid memset in querycapTrent Piepho
The v4l2-ioctl core checks the buffer type now by only allowing buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined. This driver only defines ->vidioc_try_fmt_vid_cap() so only VIDEO_CAPTURE buffers are allowed to be used with vidioc_g_parm. Also, ->vidioc_enum_fmt_vid_cap() is only called for VIDEO_CAPTURE buffers. There is no need to set the buffer type since it must already be the correct value. The struct which ->vidioc_querycap() is supposed to fill in is already zeroed so it's not necessary to call memset on it.

For read/write ioctls, all the fields which aren't supplied from userspace will be zeroed out. Zeroing code is removed from g_audio, enum_input, g_parm and gmbuf.
