I have a quest 2 on link cable and i make it run by "end tasking" all related to meta in task manager (win10), then starting the link app, exiting it, and again do end tasking all and starting link app for a secound time.
Next, start the hedseat, connect link cable, activate link.
And in 50% cases i need to do a even third end tasking-restarting process because link exits on it's own after a few secounds.
Turn off headset, diconnect cable, do end tasking, start app, start headset, connect cable, activate link from headset
Then it runs normally for hours.
