Ok. Update. Setup my psmove. (like steam vr this fails if not installed in the default directory) and ran driver4vr. It found the move and worked! I was able to move around and I could see my vive wand.
For about 5 mins anyway. Then it was back to driver4vr not started. Any further attempts to start it did the same as before where it instantly turned off. Restarting driver4vr didn’t help.
Restarting steamvr and driver4vr worked but again for only about 5 mins.
I’m ready to buy this if I can get it running reliably. Any help much appreciated.
