Bt Headset Pairing


I am trying to pair my Tekkeon Bluetooth headset with my powerbook.
My powerbook has internal bluetooth hardware and i have downloaded bluetooth update 1.5 as well as bluetooth firmware updater 1.2 but when i try to pair the device with my mac (using the BT setup assistant)i get no option for a "bluetooth headset" and when i use the "other" option i get a message that my BT hardware does not support BT headsets.
Please help
this headset is useless to me unless i can skype with it.

Thanks, Luc
