[Bug 268502] Re: Bluetooth doesn't work (hci_cmd_task: hci0 command tx timeout)

[Tony Shadwick]

Sorry to be the bearer of bad news, but the problem persists here as
well.  Please note that there is a bug in linux-firmware-nonfree.  In
order to get even this far, I had to manually symlink
/lib/firmware/bcm2033-fw.bin and /lib/firmware/bcm2033-md.hex to
BCM2033-FW.bin and BCM2033-MD.hex.  Separate bug, separate issue, but
just the same, if you're attempting to reproduce my results, that's
something to keep in mind.  This also required that I install bluez-
compat.  The hci device never gets created otherwise:
