16 * Added GoHubs GO-COM232 device id.

19 * Added old Belkin and Peracom device ids, which this driver supports
20 *
21 * 12-Oct-2000 William Greathouse
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.
