CHIRP

I am running into issues getting Chirp to talk to my newly purchased UV82. Details below:

Firmware (#3): Version NUV82
Firmware (#6): 161102N
Driver: CH340
Chirp Version: daily-20170714

The driver seems to have been installed properly (I can see it in USB Devices, no errors are reported, tried this on Windows 7 and on OS X 10.12.x Sierra).

I am getting this in the debug.log:

RadioError: Unknown response from radio

The error is pretty much identical between OS X and Windows 7.

I've looked through a bunch of stuff other people have reported and it looks like the error is not identical. Anyone has any ideas? My next step would be to try a different cable but before I go down that route, I'd appreciate if somebody could confirm that it's not code/firmware related.

Thanks!
