Greetings!

>>From my experiments with pairing to various devices I found that
presence of pincodes file (in /var/lib/bluetooth/<dondle-MAC>/)  in mode
"user" prevents
from pairing for some unknown reason, while absense
of pincodes file in mode "auto" just makes hcid fallback
to using of D-bus passkey agent.

Is it intented behavior? I suggested that in "user" mode pincodes would
be ignored...

Im using BlueZ libs/utils ver. 3.22
