CHIRP

Please re-check your cable connection and answer this questions to me:

1 - Try to read the radio with the original software, up on success and without touching the radio or cable, close the software and try to read it on chirp, what is the result?
2 - Does the radio put " - PC - " in the display just after this error arise.
3 - Try several times and see if the error is consistent: aka it occurs every time.

Cheers

Confirmed: It's a firmware incompatibility problem, I will close this to not duplicate efforts, please follow the issue #3349 for details and progress.
