hello
I just got a used 9XMi (built in 2007) over ebay from Canada.
Everything works fine except the connection with an PC.
I tried it on 4 machines now, of course with installed USB drivers.
The computers don't even register the plug-in.
Power charging does work. Conductivity of the cable is fine on all 4 wires.

Can You please give me the voltages between the 4 pins
on the back of the watch in disconnected state as a reference
how it should be?

Thanks,
