All Peripherals Momentarily Disconnect Due to BTHUSB Event ID 18 Issue.

Hello everyone,

I'm encountering a persistent issue with my PC where all peripherals briefly disconnect and then reconnect without any apparent trigger. This happens randomly, typically during video playback or gaming. The Event Viewer logs the following under the BTHUSB source with Event ID 18 at the time of these incidents:

Event Description: Windows cannot store Bluetooth authentication codes (link keys) on the local adapter. Bluetooth keyboards might not work in the system BIOS during start-up.

Here’s a brief overview of my system specs and what I have attempted so far to resolve this:

  • Motherboard: B550M D3SH (does not include built-in WiFi or Bluetooth)
  • Graphics Card: RTX 3060
  • CPU: Ryzen 5 5600x ~4.7GHz
  • RAM: 32GB DDR4 3200MHz
  • Network Card: PCIe 6E Wireless card with Intel WiFi 6E AX210 Chip, supports Bluetooth 5.2
  • Operating System: Windows 10 (64-bit - running on Crucial P3 Plus 1TB M.2 PCIe Gen4 NVMe SSD)

Initially, I used a USB Bluetooth and WiFi dongle which caused latency issues, so I switched to the aforementioned PCIe card. Despite a clean installation of Bluetooth drivers, updating BIOS, and running system file checks (dism and sfc/scannow), the issue only subsided temporarily.

In addition, I have disabled the "Allow the computer to turn off this device to save power" setting in Device Manager for all relevant devices, hoping to address any power management issues that could be causing these disconnects.

Searching on forums I've seen reports where the case connections may be causing the issue.. so I disconnected the case’s USB 3.0 connector to rule out any interference or power-related issues, but the problem persists.

Considering the detailed troubleshooting I've done, including driver and system updates, I suspect this might be related more intricately to how Bluetooth devices interact with the system or a potential underlying OS bug.

Has anyone faced a similar issue? I appreciate any technical advice or pointers that might help rectify this.

Thank you!

    I'm facing the same issue.

    USB and Bluetooth devices all get disconnected for a few seconds every 30 minutes or so. Sometimes the Bluetooth connectivity doesn't come back and the only way to get it back is to hard reset my laptop (long press the power button)

    The BTHUSB event seems to be a consequence of something else, however I'm not sure what the root cause is.

    were you able to find a solution to this? having the same problem and have tried many solutions

    I posted in another forums and got this response, it might work for you?:

    Disable your Bluetooth radio in Device Manager and see if the issue persists. If you are using an Intel wireless adapter the device to disable should be under the ibtusb.inf driver.

    Though, this sounds like it might be more of an effect rather than a cause. A commenter on this Reddit post mentioned that the heat from their GPU was causing the Bluetooth chipset to malfunction, which would make sense considering how you said it was more frequent when gaming or watching videos as the GPU temperature would increase.

    Just providing a follow up, doing some more troubleshooting and investigating.

    Found reports online of possibly a corrupt Windows activation code or something along those lines causing issues for motherboard.

    I bought a Windows 10 Pro Retail Key, upgraded myself from Windows 10 Home, and upgraded my BIOS version again to the latest version (F18d > F19).

    This has since fixed the issue and I've not encountered the disconnecting peripherals EventID 18 since!

    [!] 10/05 UPDATE: Issue is back after 3 days.
