Thank you very much for the help!
Unfortunately I have one of the newer model trackers so won't be able to make those changes.
I mentioned the tracker shows as disconnected but it does in fact show itself as connected (can see the tracker in steamVR).
The issue comes with re-configuring it to become a controller. I really need to have it appear as a controller, with the steamVR role changer but when I do try and change it in the role changer the tracker shows as 'disconnected' thus won't change.
I don't necessarily need to have 2 controllers (rather 1 tracker and 1 controller will be fine). Could I just disconnect 1 of the controllers completely from the computer and then try setup the tracker in its place?
