Dear Marcel,

I did find one solution to this:

I made an addition to the dbus-configuration in bluez-hcid.conf by
inserting paths for hci0 and hci1 for root and console like this:

<policy user="root">
   <allow own="org.bluez"/>
   <allow send_path="/org/bluez/hci0"/>
   <allow send_path="/org/bluez/hci1"/>
</policy>

After that a single listening PAN daemon is receptive on both
usb-dongles. My full configuration is attached here. It was already
previously expanded, but it was the four lines with 'hci#' that brought
the magic. I myself and probably other bluez-users, would improve our
knowledge, could you be so kind as to commenting on what additions
that could/should be eliminated from my configuration file. Please!

Best regards,    Mats E A
