○ IVT_Virtual_0000 Driver
If you have this device hanging on your device manager waiting for a driver, probably you instaled IVT BlueSoleil on your computer without installing the native Bluetooth drivers from the manufacturer first. Or, the IVT version you have is not compatible with your windows version.
I came across this issue and what i did to solve it was to:
1. Download the latest trial version, right now it's IVT_BlueSoleil_6.4.275.0 which is Windows7 compatible.
2. Extract contents of the ZIP File to a folder
3. Extract all the CAB files BlueSo~1.cab, BlueSo~2.cab, etc, using a capable application like winrar.
After you have extracted the CAB Files you should see some .inf files, one of them is for the Bluetooth PAN Network Adapter .
4. Device Manager -> Unkown Device IVT_Virtual_0000 -> Update Driver -> Point to folder where you extracted the CAB Files.
And you are done:
