+ * See Documentation/usb/usb-serial.txt for more information on using this driver
+ *
+ * 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.
