Good advice, Kevin, especially winding as many turns as practical. I
wouldn't add the extension unless a choke without it didn't solve the
problem.

The mix of the toroid's used does matter. Mix 31 is best.
Here is what I did with a USB mouse.
I bought four mix 31 snapon's and installed two 18 inches back from
the mouse and another pair 18 inches back from the connector, winding
as many turns as would fit. I bought a USB extension cable and wound
most all of it on a mix 31 2.4 inch toroid. This choke was installed
on the computer end and the choked mouse cable was plugged into that.
All of this assumes you have things properly bonded, especially the
computer case/chassis.
