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