I don't think you'll need to amplify
the signal if you use _good quality_
shielded cable. I've gone up to 50 feet
in the past with no problems. Of course
your mileage may vary and not all PC's
are built the same.

Ok... Let's see..

First of all power your mouse or keyboard from another power supply independent from the micro and that alone might solve you problem. If not you will have to put some open collector drivers on the output from the Keyb. or mouse and you can try a cmos schimtt trigger on the input but even that might not solve the problem and you will have to put a buffer on the pc side also. Better try out a heavier cable with bigger wires and better shielding.

Best regards,
Alexg
