Hi Damien,

I need more information.

May you send me the kernel messages starting from the webcam connection
up to the first ISOC data errors? Please, use the gspca 2.13.6 and set
the debug level to 0x0f:

	echo 0x0f > /sys/module/gspca_main/parameters/debug

(then, unplug / replug the webcam)

Thanks.
