As I was just getting restarted into Amateur Radio after 40 years, i decided to purchase a Baofeng UV-5 on Amazon. However, thinking I would be doing better by getting a newer model, I purchased a Pofung UV-6R. Nice little radio for 2M/70cm. However, it had one of the worst manuals I have seen; no explanations of specific items in the menus nor explanations of adjustments.
I ordered an adapter cable and downloaded Chirp figuring I could do most of my adjustments in memory via software. I used the forums and read everything I could about the Baofeng. The one thing I kept running across was that several people had to conncet and reconnect the cable to their computer to get Chirp to recognize the radio. Okay, that was something to remember.
I received my OEM cable in the mail and tried to use it. My computer would not recognize the radio. Was it Chirp or was it the cable? I did some research about the cable and learned that occasionally an error was made in manufacturing when soldering the usb modal. The receive and transmit wires were soldered backwards.
A fairly quick solution was to open the usb connector and properly resolder the wires. Eureka, its alive. Once I connected the cable back into my computer, Chirp recognized the radio and I was up and running.
