I can confirm that the patch from the review installed cleanly.
iwmbt-firmware-20230625
The patch from the comments was  applied cleanly.
World rebuilt NO_CLEAN
Kernel was rebuilt and installed NO_CLEAN
Kernel booted standalone and world installed
Ran etcupdate
rebooted
Only messages related to bluetooth were "Autoloading module: ng_ubt",  "bt0
on uhub0", and "ubt0: <vendor 0x8087 product 0x0033, class 224/1, rev
2.01/0.00, addr 2> on usbus1"
No /dev/ubt0 was present
"# service bluetooth start ubt0"
"/etc/rc.d/bluetooth: ERROR: Unable to setup Bluetooth stack for device
ubt0"

Any suggestions?
