I went to this rodeo a few months ago.
Bought two of the '82's for 222 mHz at the Paris MTC sale.
A friendly ham at the place explained how to get the thing to work.
Notet, this applies only to the red wouxun cable sold with the uv82 radios.
Here is what he said to do:
Never plug the cable in and attach the radio while on the internet.
If you do, it will go out and get a bad driver and fuck up the pc.
(I did this accidentally, and had to do a restore. I won't do that again.)
First, load chirp and then disconnect the internet.
Then, while not on the internet, plug in the red usb prog cable, attach the radio and power it on.
When it asks for the driver, load the mini cd and use the one it contains.
Start chirp and do the radio to pc thing.
As posted above by ctrmass, you must read the radio before programming and writing the radio.
Be sure the radio and cable are never attached when the pc is on the internet.
