I decided to have another play with USB and a Creative Webcam II (cpia based) -- is the past I've never had any success, only oopsen.
With pre-2.3.46-3 I don't get oopsen anymore, but I do get a complaint that the device won't accept a new address -- is this a bug of a flaw in the camera or something competely different?
I have tried with both uhci drivers; uhci.o:
