Novatek USB Keyboard/Mouse Bug
Hi, I finally figured out why my wireless mouse turns off and on randomly every once in a while and works depending on the usb hub it is in - it's the keyboard's fault.
My mouse is:

My keyboard is:

As you can see the kernel thinks it's also a mouse, which it definitely is not. I've previously posted this to LKML somewhere, and my impressions were that people don't think it's a bug, since some other model of that keyboard worked together with a mouse somehow. Perhaps that's true, but I do not have a second mouse. The kernel thinks I do, and switching the keyboard and the mouse usb hubs results in mouse devices reordering and X not working with the proper mouse (attempting to use the keyboard as mouse, which apparently does not work).

Why not just use /dev/mice and then you don't have to worry about the mice ording issue?
Also lots of USB keyboards have a fake "mouse" within them to handle some of the extended keys. It's quite common.

Hmm..didn't know I could do that - will work, I guess. Thank you.
