Ahh, the driver is back in the FC kernel. Seems that the version of
Luc Saillard (luc@saillard.org) is used.
Hey Luc,
care to pass the physical device down to the videodev registration to let
the class driver create the symlink to the physical usb device. This is
needed for e.g. HAL (hal.freedesktop.org) to recognize the device.
As an example, here is my old ov511 camera with these links:
[kay@pim linux.kay]$ ls -l /sys/class/video4linux/video0/
-r--r--r-- 1 root root 4096 Nov 21 15:40 bridge
