(In reply to George Olson from comment #8)

when I boot with 5.15.3 kernel, btusb is not loaded onto the kernel.

Results after modprobe btusb:

Hi, George, 
When you have a chance, could you try with 5.16-rc1 kernel? Yours seems
different from the above issue (like 8087: 0a2a). Just in case make sure to
cold boot after upgrading the kernel.
