  *
  * See Documentation/usb/usb-serial.rst 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.
