Hi Tony,
First of all, sorry I can't help you BECAUSE: I have exactly the same problem

.
Today, I tested the device for the first time with a VW Golf V (which uses all functions via CAN) and connected it to the OBD diagnostic port. The COM4 port appeared on my notebook, and I tested several speeds, with the engine running, and so on... but there were no logs generated at all.
When I click 'connect', it displays 'connected' (but it always says it is connected, even when the COM port appears in the device manager).
The green light on the CAN connector blinks for a second and then turns off.
I clicked 'connect' and then 'start' in the CAN-Hacker application, but nothing happens.
Is this something we have to do, or will it work if we don't?
Regards,
Andi.
