I start using a new Vive wireless adapter with my Vive Pro 2 and it also disconnects after around 5 minutes I tried every option @Bon summed up in his post. Unfortunately nothing works. I also placed a fan on top of the adapter to see if this is a heating issue. Sometimes I think is has some effect, but the adapter keeps resetting. ( HMD goes black and I hear the USB disconnect sound, followed by the USB connect sound) I so think heat is a variable because the adapter runs good for 5 minutes and after that it's getting worse and worse. It this point is keeps resetting as soon as the display lit up again.
I installed my 'old' Vive Pro 1 and this gives me the blue screen problem. After three days messing with this I am good old tethered again. Crap... will try HTC support next monday...
