I have tried it on several different computers, with the result the same on all of them. The computers are all running Windows XP Professional, SP2, and none of them have built in Bluetooth capabilities.
I have tried connecting the headset with the help of a dongle unsuccessfully. The computer seems to find the headset, but is unable to offer me any services for the headset.
I would very much appreciate if you could help me (having had very successful help from you in the past on various other topics).
