In the former the USB device is detached from the host and directly 
attached to the guest. The USB device must be connected to the host 
running the guest. In USB redirection, the USB packets are packed into 
TCP and send over network to (in general) different host which then 
unpack the packets and replays the USB packets. This is used mainly by 
SPICE where you can attach e.g. a flash disk even though the host 
running the domain is far away from you.
