I have tried all the manual install methods, drivers from the download area etc.

Before each attempt I have uninstalled the driver and ticked the box to delete the existing driver. 

The main error I get is "Device is disabled".

If I run setup.exe, it fails and says the software was not installed.

Installing manually, it appears to work but again results in a disabled device.

Trying to enable it does nothing.

In the events it has this:

Device not migrated
Device .. was not migrated due to a partial or ambiguous match.

I get similar errors using another bluetooth adaptor with the realtek chipset.

Any ideas? Thanks in advance.
