MH> this is an unauthenticated link key from SSP. Surprising to me that

That reports the same hex string, which it decodes as:

MH> Can you capture a pairing procedure with your keyboard with btmon?
MH> Then I can tell what is actually going on between these two devices.

After unpairing, it refuses to re-pair at all.  So now no keyboard
whatsoever......
