Hi,

I read SCO is only (or mainly?) for speech.
I don't use speech, but I guess it is somehow used when
SCO is enabled in the config?
Is it used by "hciconfig hci0 up", too?
(This is making problems with some, but not all dongles)

That is a great idea.
I think this could really help me finding some answers.
Hope to test it tomorrow.

Thank you for this tip, Marcel
