This patch adds its USB ID and fixes the report descriptor in the same way. Note: I don't actually have such a mouse to test, I took the report descriptor posted at https://bugzilla.novell.com/show_bug.cgi?id=774676, compared it to the one from 04d9:a067 and changed the offsets accordingly (all numbers minus 9, since it is 9 bytes shorter, and the difference is before the values that need changing). That Surely Works™.
