Hi Laurent,

Here's the steps:

1. hg clone http://linuxtv.org/hg/~pinchartl/uvcvideo/

2. wget --no-check-certificate -O frame_fix.patch
https://lists.berlios.de/pipermail/linux-uvc-devel/attachments/20091001/dba61c45/attachment.bin

3. patch -p1 < ../frame_fix.patch 
patching file linux/drivers/media/video/uvc/uvc_driver.c

4. Edited DRIVER_VERSION of uvc_driver to make sure i'm loading the
right driver

5. make && make install (logs attached)

6. depmod -ae $(uname -r)

7. modprobe -r uvcvideo && modprobe uvcvideo trace=2

8. dmesg|grep uvcvideo
uvcvideo: Found format YUV 4:2:2 (YUYV).
uvcvideo: - 640x480 (18.0 fps)
uvcvideo: - 320x240 (30.0 fps)
uvcvideo: - 160x120 (30.0 fps)
uvcvideo: - 352x288 (30.0 fps)
uvcvideo: - 176x144 (30.0 fps)
uvcvideo: - 1280x1024 (7.5 fps)
uvcvideo: device 4 videostreaminginterface 1 FRAME error
uvcvideo: Found a Status endpoint (addr 82).
uvcvideo: Found UVC 1.00 device BisonCam, NB Pro (5986:0241)
uvcvideo: No valid video chain found.
usbcore: registered new interface driver uvcvideo

9. modinfo uvcvideo|grep ^version
version:        v0.1.0-framefix

10. (Additional step) Edit /etc/modprobe.conf and add "options uvcvideo
trace=2" and reboot. (same result as 8 and 9)

Am i missing something?
