The K3 utility runs just fine through microHAM USB Device Router
as long as it is the *only* application accessing the transceiver
and you don't try to update firmware.
I have not attempted to run the P3 utility through microHAM USB
Device Router but have no need to do so. Whenever I update the
firmware in either of my K3(s) or the P3, I switch to a direct
serial connection.
