 19 * 12-Mar-2001 gkh
 20 *	Added GoHubs GO-COM232 device id.
 21 *
 22 * 06-Nov-2000 gkh
 23 *	Added old Belkin and Peracom device ids, which this driver supports
 24 *
 25 * 12-Oct-2000 William Greathouse
 26 *    First cut at supporting Belkin USB Serial Adapter F5U103
 27 *    I did not have a copy of the original work to support this
 28 *    adapter, so pardon any stupid mistakes.  All of the information
 29 *    I am using to write this driver was acquired by using a modified
 30 *    UsbSnoop on Windows2000.
