In addition to member N3051M, I would sugest you use windows xp own software for faster transfers and it also optimize the bluetooth capabilties of the the connected device, in other to do this do not install the dongle bluetooth management software, only install the drivers you can do this by pluging in the dongle, use XP'S add hardware wizard to install the drivers, then from the control panel, click bluetooth>options click turn on device discovery, follow the instructions, that's it, enjoy
