The bindings obviously work on FD account (have to select them again as Steam account just defaults them to keyboard).
Even turning PC off and on in between (not restart).
Removed X52pro and drivers from old PC and reinstalled X52 drivers a couple of times. Also tried with X52 properties open (pinky button works), but still no joy. Tried different USB 2 or 3 but as already said, works ok with FD account so this is appears to be a Steam problem. I have tried various help suggestions using 'Big Window' and I just get my X52 recognized as an Xbox 1 controller and can not delete it.
Old X52 works with FD account (so no problems with the X52.) However, the X52 is NOT recognized with the Steam account. New PC used mainly for VR, old PC used mainly in another room for peace and quiet. I have a boring X52 problem I can not solve after 2 days of trying.
