+ *    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.
