nolsen@jabra.com Aug. 3, 2016, 10:42 a.m. UTC 
From: Niels Skou Olsen <nolsen@jabra.com>

Add support for telephony device buttons and LEDs as described in the USB
HID Usage Tables specification.

This allows user mode applications convenient access to telephony devices
such as headsets, speaker phones and desk phones.
