In case of wireless USB, device connection is more complicated task then
in usual USB. So we want be able to connect wireless USB video card to
host while X server is running. 
User also don't want to restart laptop (for example) if he want to
connect it to external monitor or docking station.

Is it possible to implement special x-driver which will care about plug
and play issue of USB/wireless USB connected video cards?
