Thank you , THANK You, Thank YOU!!!




What issue do you have with USB? Are you using Windows 7?

I'm also curious about the digital artifacts over the optical connection. Are you getting noise or hum in the audio? Or do you get sudden loud pops in the audio?

So clearing the CMOS seems to be a verified fix for the Bluetooth problems with the Intel WiFi and Bluetooth adapter. I guess since I clear the CMOS fairly regularly whenever I work with the hardware in my PCs, I didn't have any problem with Bluetooth. Installing a new UEFI/BIOS version in a board includes a clearing of the CMOS, so that should also fix a problem. That it apparently doesn't is an example of how complex any networking issue can be. We haven't seen every owner of the multiple ASRock boards that use these Intel adapters complaining about them.

The Intel Dual Band Wireless-AC 3168 adapter includes Bluetooth support. You'll get two entries in Device Manager with this adapter, one for the standard WiFi, the other for Bluetooth. The adapter uses an M.2 interface, so this adapter is not permanently connected to the board. ASRock markets models of the boards that use this adapter, without it. So it is easily inserted, removed, or replaced by the user.

https://www.intel.com/content/www/us/en/wireless-products/dual-band-wireless-ac-3168-brief.html

Intel constantly provides driver updates for their networking products. Windows 10 has been a problem for Intel network products since its release. For example, the Intel wired networking adapters/chips teaming feature was broken in Windows 10 upon its release, which has worked fine in every earlier Windows versions. Just recently teaming was fixed with Windows 10, over a year later.

The latest Intel WiFi adapter Bluetooth driver, as of the date of this post, is here:

https://downloadcenter.intel.com/download/26944/Intel-Wireless-Bluetooth-for-Windows-10-?product=83418

When Device Manager refreshes, that is due to a change in the status of a device. Device status is constantly monitored, so any changes will be shown in the device's entry, via a refresh of the Device Manager listing. That's just the standard behavior of Device Manager, that we do not see very often. Yes, the quickly changing status of a device is unusual, but not impossible, and Device Manager is programmed to deal with that.

Networking device problems are not simple, and could be caused by many different things. It is very difficult to diagnose these problems without having direct access to the PC.

I have a X370 Taichi with Windows 10 pro and wanted to add my experience to this subject.  I was having problems with USB connecting and disconnecting, some crashes and other weird behavior.  I noticed Device Manager was refreshing every 2 seconds, and Bluetooth was not working.  If I deactivated Bluetooth through Device Manager the problems stopped, but when I turned WiFi on it would work but the strange continual refresh of Device Manager began again.  I tried updating, removing, and rolling back Bluetooth drivers but none of that helped.  I flashed the BIOS 3 times and each time loaded defaults, but none of that worked either.  I was about to get an RMA from ASRock and send the board back for replacement, but after seeing a post that clear CMOS helped one user  I decided as a last resort to clear the CMOS.  I was surprised to find that this solved the problem.  USB, Bluetooth, and WiFi all work normally now.  It would seem that the Intel Bluetooth chip, which also likely contains WiFi, somehow got glitched, and clear CMOS fixed it.  I don't know how this all was connected to USB, but it was.  Just thought I would share.

Hi.

I had the same problem.
However, I solved it by clearing CMOS.

A little terse concerning QC I'll say, yet I kinda understand.


sh*t happens. Things new don't work. Probably not the first and certainly not the last I'd venture to say.

This problem has nothing to do with windows 10 creators update. I rolled back to an older version and stopped updates.

My bluetooth device is now bouncing between being detected properly (but not working right), and being detected as an unknown USB device with (device identifier failed) in device manager.

It is also sometimes causing the PC to completely shut down when it cycles between detected and undetected sometimes and will not reboot until AC power has been removed for some time.

I will have to RMA the whole board apparently which in short means I will be buying another board from a company who cares a little more with their QC.

Found solution! Just unplug your PC from electricity, wait 1 minute, plug and start. Its a magic, but works LOL.

I found this issue when updated to windows 10 creators update, and many others users have this issue with AC 3168 on a board.


Odd. Are your wall outlets grounded? Maybe an overloaded power strip there?

I have the AC3168 on my SLI/ac and it didn't do that on my update to 10 Creators.

Strange.

Grounded, also i have UPS and premium class PC power supply. I check logs all that time and no one problem with electricity.

At one point, early on of the release of Windows 10 Creators update, Microsoft suggested not installing it as a new, fresh installation.

Of course, things change with updates from MS, so who knows what the current status is with the latest version.
