This USB flash drive is not compatible with Windows 7. I tried to install the key still in XP compatibility mode and it always asked me problems (same in Vista mode). The automatic purchase consulting with Jabra Halo 2 headset is not valid! The headset supports Bluetooth version 3.0 and not 2.1 key with this key Belkin! Certainly the Jabra Halo 2 headset is backward compatible with 2.1 and earlier versions, but this assumes a wait of three minutes (I timed it) before Windows detects the Bluetooth headset.
