15 | * 12-Mar-2001 gkh | |
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 | |
26 | * UsbSnoop on Windows2000. | |
