Hi,
suddenly i do not have complete log, but may be your cam do not send a
FID bit. Try to reload the uvcvideo module with NO_FID quirk:
rmmod uvcvideo && modprobe uvcvideo trace=0xfff quirks=0x10
You can find more quirks in source include/linux/uvcvideo.h or
drivers/media/video/uvc/uvcvideo.h
grep -R UVC_QUIRK_* uvcvideo.h | awk '{print $2" "$3}'
UVC_QUIRK_STATUS_INTERVAL 0x00000001
UVC_QUIRK_PROBE_MINMAX 0x00000002
UVC_QUIRK_PROBE_EXTRAFIELDS 0x00000004
UVC_QUIRK_BUILTIN_ISIGHT 0x00000008
UVC_QUIRK_STREAM_NO_FID 0x00000010
UVC_QUIRK_IGNORE_SELECTOR_UNIT 0x00000020
UVC_QUIRK_FIX_BANDWIDTH 0x00000080
UVC_QUIRK_PROBE_DEF 0x00000100
UVC_QUIRK_RESTRICT_FRAME_RATE 0x00000200
