From: Alfred E. Heggestad <[EMAIL PROTECTED]>
This driver adds support for USB VoIP phones using the CM109 chipset,
such as Komunikate KIP-1000 and Genius G-talk. Keypad is scanned and
events are reported to the input subsystem. The buzzer can be activated
by sending SND_TONE or SND_BELL to the input device. The phone keymap
can be selected in run-time by using the "phone" module parameter.
The driver has been tested with linux 2.6.24 on i386.
The patch can also be found here:
http://aeh.db.org/patch/cm109-20080205-2.6.24.patch
More testing and code review is welcome..
