Hey guys, so I got the bluetooth adapter UB400, and I couldn't make it passed the driver setup (even though it is a P'n'P) it throws this:

I have windows 10:

I tried installing the drivers for earlier versions of windows, tried to use generic bluetooth drivers, tried online update, tried sfc/scannow, tried DISM command and using third party tool to download drivers, but none worked.

Does anyone have any idea on how to fix this?

@kishikaisei I have the same problem. Did you find any solution since your last post ? I succeeded to connect UB400 on a PC with an older version of Windows 10, but on my PC with Windows 10 2004 or 20H2, it does not work (driver error). It looks like Windows 10 2004 release introduced problems with bluetooth devices and that a new driver for UB400 is required. Any idea (except rolling back to previous version of Windows ?

Than you.
