I have a strange issue: I cannot use my mouse and my headset at once.
Linux sheep 3.12.3-1-ARCH #1 SMP PREEMPT Wed Dec 4 21:45:42 CET 2013 x86_64 GNU/Linux
I plug in my Logitech Mouseman Cordless Optical Human Interface Device (Mouse) into USB.

HID isn't working any more. No mouse movements on screen. Touchpad of laptop still works.
Re-attaching the mouse has no effect. It still doesn't work. Though:

Does anybody know how to fix such an issue?
