I just purchased a UV-5R EX off of Amazon and am having trouble getting it to communicate with CHIRP. The same hardware/software config works just fine with my BF-F8HP. I get the problem whether I select Raddiodity/UV-5R EX or Baofeng/UV-5R. This is on linux, and I have the problem with the latest Mercurial commit as well as 20180906 and 20181018. I've also reproduced the problem on Windows, which also communicates just fine with the BF-F8HP just fine. I just unplug the one radio from the mic connection and plug in the other and it starts/stops working, so I'm pretty certain it isn't a driver/permissions/etc issue. This is with an FTDI-based USB cable.
The radio reports its firmware version (when holding down 3) as BFS001. I couldn't tell you whether this is correct as it isn't communicating with CHIRP so I'm not getting more than that.
I also tried fiddling with the baud settings on the serial device in linux and it didn't make any difference.
Has anybody run into issues with newer radios? Is it possible there was a firmware change not handled by the software?
I'm happy to debug or test patches/etc if helpful. The radio is just in factory config so I don't really care about losing any settings as long as it isn't bricked.
