Wireless PID:101b). Using Mythbuntu 12.04.3, fully patched, kernel version 3.8.0-35-generic the receiver, keyboard, and mouse all function correctly. Using ubuntu 14.04 (12/28 Daily) and 13.10, these devices do not work reliably. Sometimes they are not available after a reboot, other times, they will just stop responding after not being used for a few minutes. In either case, at least one reboot is required to get the keyboard and mouse to be detected and work again.
