In this case I think you can't blame UVC, because it is shown your USB
host controller can not get descriptor successfully, let alone to let UVC
driver bind the device. So I think you should first check the device. See if
its working anywhere
Hi
2.6.28 already contains uvc host driver implementation.
You just need to find out 'USB_VIDEO_CLASS' during config. then you will
have the uvc driver support

You can pull out uvc driver from the mainline linux kernel, and port to
ti-davinci kernel. Or maybe if the ti-davinci kernel is new enough, it will
already contain the uvc driver.
The uvc driver is at: drivers/media/video/uvc/

I have a Logitech Quickcam Pro 5000 which I am using with motion. The
images it's getting though have a purple tint in the brightest spots
(i.e. white t-shirt is purple).
I have seen this before but I have also not seen it before. Perhaps
it's different pieces of software driving the cam in
/input from you.
Thanks a lot.

By the way for the UVC device developing side I found the Null renderer in
DirectShow filter is very helpful for verifying the device.
I am wondering if there is anything similar on Linux side?

Even after plugged the camera in it still would not come up.
Another reload fixed it.
I could probably prove this if I knew how to delay the loading of

Another possible option is to use kopete.
To get it to work you need to compile it with a patch.

When I tried Ekiga the next morning to get the error messages, it worked!
To emphasize I did nothing in between. Did not reset the usb or power

It has to be a timeout issue somewhere?
Thanks for a very usable driver.
