Leo, Without going into a lot of detail, there are apparently two flavors of UV-5R radios with BFB297 firmware floating around. The difference in one caused a problem with uploading. So in the beginning CHIRP wouldn't work with both radios.
The important thing was that someone took the time to file a bug report (Bug #463). Eventually, after a few exchanges, additional information and files were supplied that made it possible to track down the cause of the problem.
A workaround for the issue was developed, and after some testing, an update was released.
Thanks for reporting that the update worked for you. Jim

I don't know why it didn't work with both of my radios in the begining, but it works now. Thanks, Leo
