I have tried unblock, and nothing seems to help.
Frequently when I connect my Android phone to my bluez 5.47 device I
see (btmon):

#36 [hci0]
5.709020

This is using connecting from Android 7 to Bluez 5.47.

I think this might be due to not having a default agent set which is
needed if the devices is not trusted so it would require agent
authorization.

It could also be the USB HCI race between ACL data and HCI events. It's
hard to say for sure though since the complete HCI log was not provided.
