Ookay. Thus: i have a webcam which can behave either as a Digita device, or as a usb-storage device. Personally I like the latter better (more general). When i connect the cam, it's correctly detected as a usb-storage device. The thing is that i either can't decently mount it (mount hangs and i get very much 'transfer failed' in syslogs, or cp hangs (attempting to copy the pics from the cam) with the same message in the syslogs. I'll forward a message here I sent to the lkml earlier with complete description of the problem. Hope it helps a bit more. Mail coming up.
