I don't know why it does that. You might get better debugging help from the bluez developers. There is one known case where a Broadcom (BCM) bluetooth adapter chip requires special firmware for HSP. It's a different chip than yours, but you could try to research this. If you find the required firmware (or some other way to make HSP work), please add a comment on this bug: https://bugs.freedesktop.org/show_bug.cgi?id=97064 .
