Andrew Hi,
You should now make this change more permanent in the driver configuration,
create a file named uvcvideo.conf in /etc/modprobe.d
add the following line:
options uvcvideo quirks=2
the quirks parameter bypasses some problems originated by faulty or
non fully compliant hardware.
In your case the camera fails when getting the min and max values for
the compression settings during probe,
quirks=2 bypasses this.
Laurent, you should add this camera to the uvc_ids list and hard code
the quirk there.
(This list just keeps getting bigger and bigger)
Regards,
Paulo
