Yes, but that's just because no one has written a test for a USB device.
 It would be completely feasible to plug USB into qgraph, the code for
USB in SeaBIOS is 4.5 kLOC so that's more or less the ballpark of what
you'd need.  You can then stimulate keyboard or mouse devices via
chardev (-serial msmouse), or run SCSI tests for MSD and UAS.
