What version firmware. V2.2 is latest.I got a AD600BTTL today, but it doesn't have the updated firmware. Trying to figure out how to do that now. No device at all is detected when I plug it into the USB port.
There is, apparently, a driver required so that Windows will recognize the device.
I'm just learning this. I'm a Mac user and had to buy my first in about 10 years Windows computer.
