  15  * 12-Mar-2001 gkh
  16  *      Added GoHubs GO-COM232 device id.

  18  * 06-Nov-2000 gkh
  19  *      Added old Belkin and Peracom device ids, which this driver supports
  20  *

  22  *    First cut at supporting Belkin USB Serial Adapter F5U103
  23  *    I did not have a copy of the original work to support this
  24  *    adapter, so pardon any stupid mistakes.  All of the information
  25  *    I am using to write this driver was acquired by using a modified
  26  *    UsbSnoop on Windows2000.
