Erratic RF USB Keyboard and Mouse Behavior

I don't think this is amd64 specific, but, ...

The mouse frequently becomes non-responsive, freezing in one spot. 
Moving the mouse for several seconds frees it.  Picking the mouse up and 
sitting it down does it faster.

The keyboard on a more infrequent basis stops responding.  During one 
instance, I pressed a key 8 times before the character was echoed on the 
display.

Suspecting interference, I moved the machine to the opposite side of the 
room with little or no improvement. There are no other RF keyboard/mouse 
systems nearby.

I tried changing USB ports with no change.

Any ideas?
