Add the "Off-hook" and "Speaker" LED codes 0xb and 0xc to the hid-input
configuration,
mapping them to the 0x17 and 0x1e usages in the HID usage table.

This patch is really being offered because it's what's needed to make the
operation
of the Belkin Flip USB KVM switch avaiable to user-space programs through the
HID input
event interface. The Belkin Flip KVM overloads LED usages to give software
control
over the device, providing options to flip either audio, video or both. However,
without an input mapping to the Off-hook and Speaker LED usages, this
functionality
isn't available.
It's a minor patch, adding two led codes to the EV_LED type, and mapping them to
corresponding HID usages.
This patch was created against kernel version 2.6.20.4.
