Here are a couple of patches against a copy of Greg's usb-2.4 and
usb-2.5 bk trees to add a VID/PID for Omnidirectional Control
Technology's US101 USB to RS-232 converter.  This has also been
rebadged by Dick Smith Electronics (New Zealand) as a XH6361 USB to
serial converter.  Thanks to Donald Gordon for the info, which I
have verified by checking the Windows INF files.
