Is there a mouse connected to port 2? Why doesn't it appear later?

To get /proc/bus/usb, you have to mount it (type usbdevfs). The other
problem is the babble of the Philips webcam, i.e. the device puts too much
data on USB when asked for its descriptor, this is a protocol violation.
Can anybode else confirm this behavior? If it is so, we have to re-think the
configuration descriptor acquisation...
