--- Comment #7 from jebrosen2014@xxxxxxxxx ---
I believe I have found the culprit: commit
eff2d68ca7388ee1c08811c6bbf4d8587cba01da enables btusb autosuspend by default
given a certain Kconfig option, and I confirmed that Arch Linux did opt in to
it. 


Appending `btusb.enable_autosuspend=n` to my kernel command line has
effectively solved my issue as far as I am concerned.

I had discovered that autosuspend "broke" my bluetooth device a long time ago,
but it hasn't crossed my mind for a while. The actual bug here is that
autosuspend causes the bluetooth device to stop working.
