Event ID 34, BTHUSB | Event ID 18, BTHUSB

[CheeseLiker0]

Hello! When i turn on the computer, the event log shows BTHUSB information ID 18 and then right after BTHUSB warning 34.

BTHUSB ID 18: Windows cannot store Bluetooth authentication codes (link keys) on the local adapter. Bluetooth keyboards might not work in the system BIOS during startup. Headphones are functional, they connect to other devices and they dont need addiiton drivers.

BTHUSB ID 34: The local adapter does not support an important Low Energy controller state to support peripheral mode. The minimum required supported state mask is 0x2491f7fffff, got 0xffffffff. Low Energy peripheral role functionality will not be available.

Because of this my Bluetooth headphones dont connect to the computer.

I tried reinstalling the system, reinstalling Bluetooth drivers, preventing updating the Bluetooth driver with using the Local Group Policy Editor, adding new sections and subsections in the Registry Editor and changing the power plan to Ultimate Perfomance.

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

• Press Windows Key + X to open the Power User Menu.
• Select Device Manager from the list.
• Once the Device Manager starts, locate your Bluetooth driver, right-click it, and choose Uninstall.
• If available check Delete the driver software for this device and click OK.

Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall the Bluetooth driver. 

Hope this helps! Keep me posted for further assistance.

Thank you for posting back. 

I appreciate your efforts to try and resolve the issue. I would suggest performing system factory reset will put the computer back to the original factory settings in this way all corrupted and outdated software will be removed. 

While doing the recovery there is an option to backup your personal files. If you have not previously done one now is a good time.
