Subject: Kernel 3.2 and Broacom BCM20702A0

Hello,

I was eagerly awaiting kernel 3.2 as it has support for the usb
bluetooth builtin adapter in my new laptop, a Fuijitsu Lifebook E751.

To my disappaointment it doesn't seem to work right.

Output of usb-devices:

T: Bus=02 Lev=02 Prnt=02 Port=03 Cnt=03 Dev#= 5 Spd=12 MxCh= 0
D: Ver= 2.00 Cls=ff(vend.) Sub=01 Prot=01 MxPS=64 #Cfgs= 1

S: Product=BCM20702A0

C: #Ifs= 4 Cfg#= 1 Atr=e0 MxPwr=0mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=01 Driver=(none)
I: If#= 1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=01 Prot=01 Driver=(none)

I: If#= 3 Alt= 0 #EPs= 0 Cls=fe(app. ) Sub=01 Prot=01 Driver=(none)

Seems to be another vendor specific ID for the same adapter...

For a quick test I did load the btusb module manually and did a
'echo "0489 e031" >> /sys/bus/usb/drivers/btusb/new_id'

'hcitool dev' then shows my BT adapter's MAC. It seems to work but it
does not find any other devices.

Under windows XP in a virtual machine all is working well.
