USB devices add to your com ports.
Reassign the one that your OBD is using to one in the range that your softare will recognize.
So I am having some major COM port issues. I have no clue what is going on, but I am up to the point where I have com port 1,2 and 10,11,12,13,14,15,16... My port 10 is GPS and 15 is OBD2... But my OBD program only shows Com port 1-8 so I cant actually use it. How can I go back erase all of my COM ports?
So how do I reassign them though? Because it automatically assigned those values to them. I thought I had to go through the registry and change some values to 0.
