We've merged quite a few changes for the uvcvideo driver recently. Bisecting the problem would help greatly. It could also be helpful to set the uvcvideo module 'trace' parameter to 0xffff (e.g. add `uvcvideo.trace=0xffff` to the kernel command line, or unload and reload the uvcvideo module with the parameter set to 0xffff) and give us the additional messages printed to the kernel log. Could you also provide the output of `lsusb -v -d 0c45:670c` (running as root if possible) ? -- Regards, Laurent Pinchart
