Subject: [PATCH v2] HID: logitech-dj: allow mice to report multimedia keycodes

From: Yaraslau Furman <yaro330@...il.com>

So, I think this should work fine for now, but IMO we should see if it's
possible to allow the driver to receive all events that a keyboard can send,
since Windows application can assign pretty much any keycode to any mouse
button (perhaps not the main ones though), and then we might see the same situation again.

I tried doing that on my system but the driver stopped working completely.
