Hello, I have a problem using my Callstel "Black Tube" Bluetooth Headset with my Windows 7 Notebook. The headset is a standard mono Bluetooth Headset (no A2DP I think). It can pair it with my Laptop which runs Windows 7 Professional and it is also shown in Devices and Printers, but it is not shown in the System Control as an Audio Device. In additiom to that Windows says that there is no proper driver for the bluetooth peripheral device installed and it doesn't find the driver with windows update. I didn't get a driver CD from the manufacturer and the support says that this product should run without special drivers because it is a standard mono-bluetooth headset that uses only standard protocolls. Do you have any suggestions what to do?
