I'm currently running Parrot OS and it was working normally, but recently my USB Bluetooth adapter stopped working (it was working yesterday). Since I'm using the default config and haven't changed or installed anything recently to cause this, I suspect it was a recent OS upgrade, since that's the only thing I've done to cause this.

Basic info:

uname -a:

Linux parrot 5.14.0-2parrot1-amd64 #1 SMP Debian 5.14.6-2parrot1 (2021-09-25) x86_64 GNU/Linux

What I've done so far:

  • I've tried rebooting my system, of course, both within the OS and by physically removing power from the motherboard.
  • I've tried moving the adapter between USB ports and re-seating the adapter.
  • I've tried restarting the Bluetooth service
  • I've tried reloading the kernel module.

Sources I've already found, that didn't seem to help:
