OK. Unfortunately, that sounds like you have the new driver, but it’s defective.

One last thought - there was a buggy version out there that ran at double speed, so you had to half-press really fast to get it into programming mode. Those drivers were supposed to have been taken off the market, but somebody somewhere got their stock mixed up, so they still crop up from time to time.

If that doesn’t help, then I can’t think of anything else; you probably have a defective unit. Ask BangGood for a refund. After that, Convoy sell replacement drivers if you want to try your hand at a fix (you have to unsolder & resolder a couple of wires).
