Seems your extfeatures is telling you something different from what it really
supports. Can you try with the following diff (use the dynamic debug that Andre
told you)
Attached. The result is "features: 0xff".
I suppose that (should) mean(s) "all features"; if that's not actually a
valid possibility due, perhaps, to undefined or mutually exclusive bits
then maybe it's an option to take 0xff to mean that the adapter doesn't
in fact support any of them?
Also the output of hcidump would nice.
If the below (which is what hcidump spit back at me at some as far as I
could determine random moment) is not what you wanted, I believe you
will need to specify which action to take while monitoring things with
hcidump.
