17 *
18 * 12-Mar-2001 gkh
19 * Added GoHubs GO-COM232 device id.
20 *
21 * 06-Nov-2000 gkh
22 * Added old Belkin and Peracom device ids, which this driver supports
23 *
24 * 12-Oct-2000 William Greathouse
25 * First cut at supporting Belkin USB Serial Adapter F5U103
26 * I did not have a copy of the original work to support this
27 * adapter, so pardon any stupid mistakes. All of the information
28 * I am using to write this driver was acquired by using a modified
29 * UsbSnoop on Windows2000.
