Mike,

One of the potential problems is that the K2 works at 4800 baud, which 
by current standards is slow.

The problem is that some USB to serial adapters do not like to run at 
that slow speed.  I have tested the Elecraft KUSB with my K2, and I also 
can state the my 4 port Edgeport USB to serial converter works well.
I have also used a Keyspan adapter.

If you can arrange a "return if it does not work" arrangement with the 
place where you buy it, that would be beneficial.
You can use a USB 1.1 or 2.0 or 3.0 adapter.

73,
