As of 12/14 I updated to the latest: The Quest to 12, installed the PC sw and drivers on an Intel NUC w/ i7 6th gen w/ external GTX 1070ti via Thunderbolt.
With a 1m USB-A to USB-C cable the PC sw recognizes the Quest. (with a different one it does not)
There seem to be two approaches to start Link:
1) I have not yet found out what (and when) the modal Link dialog is triggered on the Quest, but when I start Link, after a few seconds of dark with hash-marks I land in the normal Quest environment.
2) If I trigger Link from Settings > Devices the effect is the same.
Questions popping up:
Could the Link failure be related to my external-GPU-setup?
When and how is the modal Link dialog triggered on the Quest?
Why is the Link button located in Devices and not in Experimental? (BTW: The new hand tracking works very nicely for a first beta!)
Thanks for any insights to make Link work!
