I'm trying to use my Samsung WEP470 bluetooth headset with Windows 7 for VOIP apps. When I try to "Add a Bluetooth Device" in the control panel, it detects the headset and installs a driver. However, at the end of driver installation, I see the error message, "This device cannot start. (Code 10)" I'm using the Microsoft Bluetooth transceiver that came with my Microsoft IntelliMouse Explorer for Bluetooth, and the mouse works fine. From other Superuser.com posts, it looks like the headset should just work, as long as I have the Bluetooth transceiver's drivers properly installed. Any ideas what I'm doing wrong?
