How about the 2-EV* and 3-EV* packet types? The spec says that a 0 for these bits means they have been enabled.
Shouldn't you also check for their support in the feature mask?

How did you mangage to set up an eSCO since you are using only HV* packet types (ESCO_PTYPE_MASK)?
Or is it because the 2-EV* and 3-EV* bits are "0" thus the controller thinks you want to enable those packet types?
