My Bluetooth headphones used to pair with no issues on my Windows 7 x64 installation until yesterday. Whenever I turn on my headphones, it shows up as “Standard Serial over Bluetooth Link (COM21)” in the Device and Printers window. This is the only Bluetooth peripheral I have installed on this desktop machine. The dongle is a Asus USB-BT400 and the headphones are the LG HB 750. The Asus USB-BT400 uses the Bluetooth 4.0 standard.
I’ve tried reinstalling the WIDCOMM drivers a few times, but that hasn’t helped. I’ve also tried removing the BT ENUM keys in the registry before reinstalling the WIDCOMM drivers, and that hasn’t helped either. I also tried repairing my headphones with the BT adapter, but the head phones do not appear when I go to the ”Add Blue tooth Devices” window. The adapter does not show my head phones for pairing, even though it is in pairing mode.
One interesting thing is that the dongle does pick up other Bluetooth devices, such as my printer.
Does anyone know how to get the Bluetooth software to recognize my head phones again?
Here is a screenshot of the windows mentioned:
