I still have this issue all the time, spent an hour on it last night. Double-check that developer mode is on in the occulus iphone / android app. Then switch ports around. That's the only way I finally got it detecting again.
I believe these challenges prevent functionality. Researching "Device not detected" (quest 2/computer/developer, etc) leads to multiple advised downloads (sidequest, developer hub, drivers, etc. etc. etc) soon, we become whooped. Please keep kids safe while working on a simple solution for those suffering TBI's.
Thank you for your attention to this matter.
PS--- "Device not detected"
