I am pretty certain that you didn’t want this quirk:

        /* When this quirk is set, the HCI Reset command is send when           
 
         * closing the transport instead of when opening it.

This quirk is for Bluetooth 1.0b devices where the HCI_Reset behavior was not 
clear or for devices that actually misbehave with the initial HCI_Reset.

In addition, you commit message is totally misleading. That is not what is 
happening with this quirk.

Regards

Marcel
