Any other wireless devices around; phones, remotes, ect...?
Have you tried to start the computer on, with them already plugged in?
Have you thought about using a toothbrush on it? Get it BLUEtooth?
OK, so maybe that wasn't very funny.
Have you tried a different port, assuming that they are USB?
Have you tried a wired keyboard in the same port?
We are all curious like a cat. We wonder, we ask, we learn.
Please post back when a suggestion works, so that others may learn.
