USB Connector Managers>UCM-UCSI ACPI Device error 43 in NUC11PAHi7 and USB-C doesn't work

Hello,

I have a UCM-UCSI ACPI Device error 43 showing up under USB Connector Managers in Device Manager of my new NUC11PAHi7 running Windows 11.

I think it's related to USB-C since it doesn't work when I plug in a pen drive that has a USB-C connector. This pen drive works fine when plugged into my Android phone USB-C.

There are some previous posts on this issue and I've already tried the following methods, but nothing works:

- Update BIOS and drivers to the latest by Intel Driver & Support Assistant.

- Disable/enable the device.

- Uninstall and Scan for hardware changes.

- Shut down and unplug the power adapter then plug in and turn on again.

- Move from Windows 10 to Windows 11 with a clean install (same problem in Windows 10).

Please help. I really hope this is a driver issue and can be fixed with an update.

Thank you.

Hello BiboBB,


Thank you for posting on the Intel communities. In order to have a better understanding of the issue, please share with us the following information: 


  1. Was it working before? If so, when did the issue start happening?


Also, please download and install the Intel System Support Utility (Intel SSU):

https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- 

Open the application and select "Everything" click on "Scan" to see the system and device information. By default, Intel SSU will take you to the "Summary View". Click on the menu where it says "Summary" to change to "Detailed View".  

Click on "Next", save the report and attach it to your response.

Hello Josue,

Thank you for your reply. To answer your question:

 

1. Was it working before? If so, when did the issue start happening?

No, it wasn't working before.

My NUC is brand new and I was installing Windows and applications when I found out about the error. Events log shows the problem started as soon as I installed Windows 10 21H2. The same thing happens when I started a clean install of Windows 11. I attach a screenshot of the error on Windows 11. I tried deleting and scan for hardware changes a couple of times.

 

I also attached the SSU scan results. Please take a look.

 

Thank you,

Hello BiboBB,


Please try performing the following steps to try to solve the issue:


1. Load the BIOS defaults

2. Start Windows, then shutdown.

3. Remove the power supply for at least 1 minute

4. Reapply power and boot again. (In some cases one more reboot is needed)


Please let me know the results of the troubleshooting.

Hello Josue,

 

Thank you for your response. I tried the troubleshooting:

 

1. Load BIOS defaults (F2 on startup, F9, F10)

2. Start Windows, shutdown.

3. Remove power cord of the NUC for a 1-3 of minutes.

4. Reconnect power and start.

 

Unfortunately the problem persists. There's still a UCM-UCSI ACPI Device error 43.

I repeat step 3 and 4 many more times (actually I did it a lot of times before) but it still didn't work.

 

Can you reproduce the problem with a new NUC 11 and latest Windows 10/11 from your side?

Otherwise this can be just another mystery of hardware + driver + Windows issue and let's hope it will resolve itself with a future driver/OS update.

 

Best regards,

Hello BiboBB,


Thank you for the information provided, please try performing a CMOS reset using the security jumper, in order to do this, please follow the next steps:


1. Find and remove the onboard configuration jumper (yellow jumper).

2. Plug in the computer to a power source and power on the computer.

3. The computer displays the Config Menu.

4. Select [2] Clear BIOS User and Supervisor Passwords.

5. Power off the computer and disconnect it from the power source.

6. Place the configuration jumper back to its original position.

7. Replace the cover.

8. Plug in the computer to the power source and power on the computer.


Let me know if this works.

Hello Josue,

 

I tried the BIOS security jumper troubleshooting but still it didn't work.

Between step 2 and 3, there were confirm screens of reverting to factory BIOS version but I simply press Esc and went to Config menu and press 2.
