I don't have any detailed information about the Transilica chip. Run
"hcidump -x" as root and if you see SCO packets then this dongles routes
the SCO data over HCI, otherwise it goes over the PCM.
And btw. do you activated the HCIUSB_SCO kernel option and do this
dongle really have the needed ISOC interface? You must check the content
of /proc/bus/usb/devices.

Marcel
