I'm not sure, learning as I go. Did you try hardware compatibility lists
(HCL), like the one at linuxquestions.org and other places? Maybe you could
find what you need there, since then you know other linux users are using it
with success.

Yes, it seem so but does this feature <EDR ACL 3 Mbps> not indicate that
its a 2.0 device?

The error messages also look like those when eSCO gets sent to a SCO only
device. Maybe it's possible for bluetooth 2.0 devices to still be SCO-only? I
don't know the qualifications ...
