[Elecraft] K3 stopped communicating

[stan levandowski]

My K3 (#5244) mysteriously stopped working with HRD.  It had been 
working FB for months.  HRD claimed it could not connect with the K3. 
I then tried it with the K3 Utility and I got the following:

Xe2000011 Bootstrap loader did not echo a D
MCU Firmware load failed

It's a K3/10 which I built and it works just fine except for this.  The 
USB cable is the Elecraft product.

So far I've downloaded a 'fresh' copy of the utility, cold-started the 
system, and reviewed the process.

I'm not particularly computer-literate when it comes to this new-fangled 
stuff and I'm becoming less enthusiastic every day ;-)
(Gimme a System 360/Mod 67, a bank of 2400 bpi tapes, and assembler 
language any day!)

Any suggestions would be appreciated.  My gut feel is that it's in the 
K3.  The sudden cessation of communication with HRD for no apparent 
reason makes me think this way.
