Hi Laurent, I've applied the patch with the latest hg and it didn't work.
modprobe -r uvcvideo ; modprobe uvcvideo trace=2 gave me:
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 3 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
Best regards,
