[kju:] USB Support
Q(EMU) supports USB devices. Q(EMU) emulates a USB hub for the guestPC. The guest PC can add virtual and real devices to that hub. At the moment, Q only supports virtual (simulated) USB devices. One of the more usefull devices is the USB tablet, allowing to use the mouse inside the guest without "grabing" and "ungrabing".
There is a initial support for real USB devices on linux. But the libraries used for that do not run on OS X yet.
