Hello, my Vive pro is not working with steam vr. I have a repeated problem of error 208. I have tried, unplugging my VR headset, turning the generic USB power off, restarting steam vr, uninstalling steam vr, re installing HTC Vive setup, a few other solutions that proved to be unfruitful. Please help, I have been working on this for around 4 day. Thank you for your help!
