BUG: UVCVideo not working in Ubuntu 8.10 kernel 2.6.27

There seems to be a change in how uvcvideo works in 2.6.27 that cause motion to not work with the device.

This is the output

Hi, I am running on Ubuntu 8.10 kernel 2.6.27-11-generic with a Quickcam Pro 9000 (UVC) and it does work for me.
I have exactly the problem described on an NSLU2 running Debian 2.6.26-1-ixp4xx, both with Motion 3.2.9.
On the NSLU2 the problem appears as soon as I specify a size other than 320x240. I guess on the slug I will
try with a newer build first.

I've tested motion trunk-r442 with ubuntu 8.11 kernel 2.6.27-12-generic and stock uvcvideo without issues.

Please try to reproduce with trunk.
