I must be missing something here.
I agree that it must be on driver side but I'm looking at this small webcam
driver
svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk
udevinfo -a -p $(udevinfo -q path -n /dev/video0)
gives this :
ATTR{name}=="Laptop Integrated Webcam"
but I cannot find this string (or even substrings) neither in the driver nor in
the kernel sources.
Hum...the data (like the name) must come from the hardware.
