Bob is right about cables, but things like USB hubs also need to
be considered. When I transmitted at more than 100W on certain
bands, my 7 port USB hub would lock up and need to be power
cycled. It has a plastic case, so I got a metal box to house it,
and a ferrite clamp on choke for each USB cable coming into it.
I stuffed all of them into the box, bonded the case to the shack
bonding system, and haven't had a problem since.
(The hub supports my external keyboard, mouse, backup drive the
K3, and a cable for syncing/charging my cell phone.)

Yes both channels supported. Regarding USB cables, the
standard A Male to B Male is the configuration. Be sure to
look for and get good quality cables which do have a
shield. This will mitigate many RFI issues associated with
the cable picking up RF and allowing it to get into the
computer. Of course a couple of turns through a ferrite
donut on the cable will also help.
