you should edit kernel source. find drivers/media/video/uvc/uvc_driver.c
and add some thing like this:
{ .match_flags = USB_DEVICE_ID_MATCH_DEVICE
| USB_DEVICE_ID_MATCH_INT_INFO,
.idVendor = 0x046d,
.idProduct = 0x08c1,
.bInterfaceClass = USB_CLASS_VENDOR_SPEC,
.bInterfaceSubClass = 1,
.bInterfaceProtocol = 0 },
replace idVendor idProduct to yours. Try it on your own risk. If your
cam will be in fire, i have no responsibility.
