Thanx for the quick answer.
It is a bluetooth dongle. Using the provided drivers under XP, works as a bluetooth dongle and managed to sync my Pocket pc with Outlook, transfer files etc on an old Compaq 1200. When i got it (~3 years ago) it was advertised as a new kind of bluetooth dongle, and to support sound over bluetooth (Until now if you Google for ma-720 you'll find the adds). I bought it to use my bluetooth headset with skype/voipbuster (never did thow cause i'm on Ubuntu ever since:)). Maybe the sound thing causes the problem and making it an anusual dongle .

Thank you again for your time and help!

Regards

Eugenios
