Hmmm. I seem to have a similar problem on my B4. I'm using elm327-usb interface and my LED's seem to behave in the same way, except for changing of power LED. Used Proscan and Digimoto however the best result was that I had live data for Coolant and Air intake temp, nothing else.
When I looked at the log, there seems to be no response to any other codes.
I'm starting to think that I may have a fault interface but can't tell for sure since it's new and I never used it successfully.
May give it a go on another car to eliminate at least one factor in this puzzle.
As to the ports and communication problem I would check you ports again especially if you are using a bluetooth dongle. I have one and if I try to map my usb port to com3 (which is used by bt serial) I can't get it to talk through obd2 software. This is after making sure that port numbers have been manually remapped to avoid any conflicts. Try to set a higher port that has not been used before for anything else.
Anyways, if there is someone out there that knows the solution to our issues it would be great.
