I’d use a #31 mix snap-on and wrap several turns though it. I purchase mine
from Mouser. I don’t have the PN handy but if you need it let me know.
Those from RS I don’t count on to do a good enough job.

OK, Say you get RF into a USB keyboard. It just stops working and the only way
to get it working again is a total re-boot.
I'm assuming the best option is ferrite beads on the cable.
Now question, where is the best placement of the beads. Keyboard end? Computer
end? BOTH?
I have two here, a small one where I could get one or two passes through the
hole. ( it is a Radio Shack split thing )
and then a much larger one, also split,, but the hole is close to a inch ID. so
I could do many turns.
What would be best to put where?
