Ian,

> You might like to try a v4l uvc driver and see if it works for you.

Sorry for the late reply.

I've been trying USB2.0 UVC webcam too, but I have not succeeded yet.
I dumped urbs and saw no errors in isoc-urbs.

My testing environment is the following,

UVC driver:

I checked out the recent driver fromhttp://linuxtv.org/hg/~pinchartl/uvcvideo/


Webcam:
* Logitech QuickCam S5500 (046d:09a1)
* Logitech QuickCam E3500 (046d:09a4)

App:
* luvcview (ver. 20070512)

Results:
luvcview outputs "Ignoring empty buffer ..." and exits with errors.

Regards,

Noboru
