I'm running a 2.6.9 kernel and the latest bluez packages, but the USB dongle 
(a Lifetech BlueConnect) and the headset (a Plantronics M2500) don't work 
together. Having hcid running and hcidump on the background when I do 'btsco 
00:03:89:77:4D:10 2' I get :

If I leave out the channel (2) it claims it can't connect to the SDP server, 
because of timeout.
Currently the only thing working is 'hciconfig' and 'hcitool scan'. By the way 
'hciconfig -a' reports :
