John: I wouldnt try it. Both Elecraft and MicroHam disclaim it.
Here is what I do: My Ham Radio computer has a dedicated Serial port. I have two MicroKeyers (an original and a 2) which I use to drive my K3 and my secondary TS570. Both of these are driven by single USB cables. Since the K3 requires exclusive access to the serial port for config and upgrades, I have purchased a very inexpensive ($8 new), RS232 one by two data switch. I plug the MicroKeyer 2's serial CAT connector into one section and the serial line from my computer's single serial port to the second connector. I then place a gender changer on the common DB9, then place a RS232 cable from that DB9 to the K3 CAT connector. When I need radio control from my logging programs, I "patch" the MicroHam control through to the K3, when I need to upgrade software, I place the switch in the other position and "patch" the serial port directly from the computer into the radio. No issues and no problems in two months of K3 operation (with many software upgrades accomplished).

I know it was possible but after the loader was originally upgraded there was a possible glitch that would cause the firmware load to fail. My firmware is at 2.38 and I think it is time to come out of the Dark Ages once again.
