The USB Devices are named as usb_device_vendorID_product_ID_serialNo
(noserial if there is no ASCII serial number).

The parent may be important, so the output of lshal may need to be
properly known, but you could also just set it to the dummy
/org/freedesktop/Hal/devices/computer value (i.e. its parent is the root
of the tree).

If this works for both dvb and v4l, we could remove the patches in hal,
and just have webcamd do our dirty work.
