2 * Definitions for Belkin USB Serial Adapter Driver
5 * William Greathouse (wgreathouse@smva.com)
7 * This program is largely derived from work by the linux-usb group
8 * and associated source files. Please see the usb/serial files for
9 * individual credits and copyrights.

12 * it under the terms of the GNU General Public License as published by

14 * (at your option) any later version.
16 * See Documentation/usb/usb-serial.txt for more information on using this driver
19 * Added old Belkin and Peracom device ids, which this driver supports
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.
