[Elecraft] K2 - KUSB PROBLEM

[eric norris]

My K2 does not work with my KUSB when using HRD.  I get a constantly changing freq display (of different lengths), and the other fields such as NB do not read correctly.  

HOWEVER, there are no problems when using an older Keyspan Serial Adapter on the K2.  Hooked up to the same computer, HRD works fine.  ALSO, when using the K2 with an XV transverter it works fine as well.  I am using the KUSB to connect the K2's KIO2 cable to the computer--not a direct hookup between the K2 and the computer.

From this I concluded that the KIO2 and cable were not the problem.  The problem was the KUSB.  I told my sad tale to Elecraft Support, and they gleefully sent me a new KUSB.  It works just like the old one, which is to say it doesn't work!  

I am using the latest firmware for the KUSB.  The KUSB also does not work with a serial card (PCMCIA) plugged into my shack laptop.  This serial card is normally used with my K3 and works FB.  

Does anyone have a clue as to what could be wrong?  There must be many K2 users out there using a KUSB to communicate with their computer. 

Thanks,
