I had this issue recently and it was a file permissions issue on /dev/ttyUSB0.  Make sure you have write permission.

I am working with several radios some of which I expect not to work so no
problem.  However if I hook up a Baofeng UV-6 and ask chirp to do a
download via ttyUSB0 under Ubuntu 14.04 I get "Radio did not respond"
error.  Nothing else shows in the log even if I use debug level and
verbose settings.

Radio connected with it's proper cable and volume on full (though I have
tested it at various volume settings).  I get the expected errors if the
cable is not plugged into the computer so I assume it is reading the port
correctly.

Any suggestions on what I may be doing wrong?

Thanks
