I recently bought a BTech UV-5x3 and found that the Wouxun cable works just fine for it...sort of. I had to trim away a lot of the rubber/plastic so it fits all the way into the radio. On my Win7 machine I had no problem loading frequencies. My Win10 machine, however, was a different story. It kept replacing the working cable driver with the "best" driver that doesn't work at all. So I cracked open the USB end and replaced the Prolific interface with an FTDI interface. After finding out that the RxD and TxD wires are reversed, I got it going on both machines. The load from a stock source is a real nice touch!
