Bluetooth missing after Win10 update 2004

2020-06-11, 21:30 PM

Hi!

Updated Windows 10 to latest update 2004 and now my Bluetooth is missing; early worked well.

My Lenovo PC is Y720 Cube-15ISH Desktop (ideacentre) - Type 90H2, shortly aka Cube, a desktop "gaming" computer.

On Device Manager I can see one unknown device, but it says it is USB-device. I have disabled and unstalled it. No cigar.

I downloaded here and installed QCA BlueTooth Driver for Windows 10 (64-bit) - Desktops version 10.0.0.325 here, but didn't succeed.

I have run Windows 10 own troubleshooter. It said that my Bluetooth device is missing or driver not installed.

I have run Windows 10 security & update. And no cigar.

So, how I get my Bluetooth back?

MSInfo tells about this Unknown Device: USB\VID_0000&PID_0002\5&1E5393C&0&9 and error code 43. Can someone explain what this mean?

Welcome to the Community

 

I didn't find your Cube on the list of tested devices for Windows 2004 compatibility, so I started looking around and found this article. Excerpt

 

Microsoft has found that certain versions of drivers for Realtek Bluetooth radios aren't compatible with Windows 10 2004. It's implemented a block on the Windows 10 2004 rollout to devices with affected Realtek drivers until they've been updated.

 

..that's assuming your Cube shipped with a Realtek card.  If so, you could try rolling back to 1909 until those new drivers are pushed out.

I solved the issue. USB port 9 was in trouble and marked triangle. I just plugged my USB webcam to it and Bluetooth come back. Yes, this so weird, but it solved the problem. Seems the USB port make the issue. Haven't solved problems early like this. First time.
