16 | * Added GoHubs GO-COM232 device id. |

19 | * Added old Belkin and Peracom device ids, which this driver supports |
20 | * |
21 | * 12-Oct-2000 William Greathouse |
22 | * First cut at supporting Belkin USB Serial Adapter F5U103 |
23 | * I did not have a copy of the original work to support this |
24 | * adapter, so pardon any stupid mistakes. All of the information |
25 | * I am using to write this driver was acquired by using a modified |
