I've got a Dell 1520 with the "Omnivision Laptop Integrated Webcam"
(0x05a9/0x2640). Adding the standard block gets the camera recognized
and mostly initialized, but then it bombs out with "Failed to query
(135) UVC control 1 (unit 0) : -32 (exp. 26)." As far as I can tell,
that's from the URB layer trying to talk to a closed/missing endpoint
(not totally certain, it's been a long time since I worked with the USB
guts and the APIs might be different).
Does anyone have any ideas about this? I'm pretty stumped, though it
doesn't help that I only have a vague idea how UVC works =)
This is an Ubuntu Gutsy Gibbon system with the default kernel.
Thanks for any help you can offer!
