The kernel logs you attached to your e-mail clearly show that something is
going wrong with your camera even before the UVC driver kicks in. For
instance, the third log file shows
[ 6.976000] usb 6-3: new high speed USB device using ehci_hcd and address 3
[ 7.128000] usb 6-3: config 0 has too many interfaces: 97, using maximum
allowed: 32
[ 7.128000] usb 6-3: config 0 has an invalid descriptor of length 0,
skipping remainder of the config
[ 7.128000] usb 6-3: config 0 has 0 interfaces, different from the
descriptor's value: 97
[ 7.140000] usb 6-3: configuration #0 chosen from 1 choice
[ 7.140000] usb 6-3: config 0 descriptor??
The kernel can't even read the USB descriptors.
There are several possible causes for those kind of issues. The camera can
completely buggy (even if it seems to work under Windows), the EHCI
controller isn't playing nicely with the camera, or you got bad
cables/electrical noise issues.
Could you try with kernel 2.6.26 ? There have been quite a few EHCI driver
improvements compared to 2.6.22. If it still doesn't work, you should report
the issue to the linux-usb mailing list.
