Hello,
I just bought a D-Link DBT 120 rev B3 from ebay and flashed
it with the latest Apple dfu firmware using btdfu. (Thanks
for the advice, Marcel!)
Before the firmware upgrade, it talked to my Logitech Mobile
Freedom headset fine (Logitech HS02-V07) using btsco, but
the connection cracked and popped a lot. I run an 802.11b
network, so I figured the BT 1.1 might be getting interference
from the 802.11b net, thus causing the sound artifacts.
After the successful upgrade, it sounds a little better, I
think, but how do I make sure that the USB adapter AND the
headset are using BT 1.2's AFH features?
Here's my adapter:
hci0: Type: USB

And here's my Mobile Freedom Headset:
# hcitool info 00:0D:44:36:E6:F4

# hcitool afh 00:0D:44:36:E6:F4
AFH map: 0xffffffffffffffffff7f
Does this indicate that both devices are using AFH correctly?

monitor the "hcitool afh" call and if the value changes then AFH is
working.
