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 over CAN) and connected it to OBD-diagnostic-port. The Port COM4 appears on my Notebook, and I tested several speeds, and with running motor and so on...but no logs at all...
when I click on connect, it displays connected (but it always says it is connected, when the COM-Port appears in the device-manager)
the grren light at the CAN-Connector blinks for a second and then disappears.
I clicked in the CAN-Hacker-application on connect an then start...nothing happens
something we have to do, so it will work?
