After initial teething problems, the dongle works! F8T016 now under Windows 7 64bit. The initially installed original Windows Bluetooth driver did not work properly, because it lost my keyboard (Logitech Media Board Pro) repeatedly or did not connect. The downloading new drivers from the Belkin site proved somewhat difficult, therefore only four stars: To download a serial number is required, but this is not on the dongle available. Trick: Fill the serial number on the form with zeros, then download the current "drivers". This is actually a Broadcom Installer, which then herunterläd and installs the necessary drivers for the dongle. Now everything works.
