So if you have isoc=2 it fills up your syslog. Can you extract some of these SCO packets with hcidump for me. My problem is now that I can only fully blacklist the SCO support for this dongle. I can't force the Bluetooth core into using 8-bit only. Any chance of a name or identification of this dongle?
