[Elecraft] K3 lost comm with K3Util

[nr4c]

Are you trying with the compuyter power supply plugged in?  If not, try 
it.
Your computer's USB port may be marginal on battery power.

Also, try a USB-serial adapter with FTDI chipset.  These seem to be the 
most
easily used.  Also try to find a computer with a serial port to try.  
maybe another
laptop.  Don't give up!
