Thunderbolt DCH Driver Intel Nuc 10th Generation

[JohnKa]

Community,

I have installed my windows 10 OS and all the drivers on my Intel NUC (Thunderbolt 3 Version 15E8). My Sonnet 10GBE Thunderbolt 3 Adapter worked well with Microsoft Thunderbolt Drivers. After updating Windows 10 OS, the legacy driver was replaced with the new Intel DCH Thunderbolt 3 Driver (Version 1.41.1094.0) From this moment, the Sonnet Thunderbolt 3 Device stops with ErrorCode "Der Gerätestart wird blockiert, weil der Benutzer nicht angemeldet ist. (Code 55)" that means the start of the Device is stopped, because the User is not logged in. I have checked the Thunderbolt Sonnet 10GBE Adapter on another System (Dell XPS) with Thunderbolt 3 (Version 1575) and everything works well. Even the window pops up with asking "do you want to accept one time or for ever". This is not poping up with Intel DCH Driver (1.41.1094.0). In fact, that I cant revert to old or legacy drivers, hopefully someone knows that problem and got a solution for me. Thanks in advance.

Hello @JohnKa

Thank you for posting on the Intel® communities.

In order to check this further, could please provide the following details?

1- When you say "the legacy driver was replaced with the new Intel DCH Thunderbolt 3 Driver", did you mean the Operating System updated (pushed) the driver? For instance, through Windows® Update service?

Or did you download and install the driver from the Intel® Download Center?

2- After installing the new DCH Thunderbolt* driver, was also the Thunderbolt Control Center software installed? (available on the Microsoft* Store).

3- We understand that you tested the Thunderbolt* Sonnet 10GBE Adapter on another System. By any chance have you tested another (different) Thunderbolt device on the Intel® NUC?

4- Run the Intel® System Support Utility (Intel® SSU) to gather more details about the system.

• Download the Intel® SSU and save the application on your computer
• Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".
• To save your scan, click Next and click Save.
• Once you have saved the file (.txt file), please attach it to your reply.
• To upload and attach a file, use the "Drag and drop here or browse files to attach" option below the response textbox.

Hi AndrewG_Intel,

good news. After installing the new Bios update "Intel® Aptio* V UEFI Firmware-Integrator-Tools" Version 4.0 from 26.04.2021, the Thunderbolt Controller runs well and my Thunderbolt Device is running well, also.

Just a minor question: The Thunderbolt Device works/acts only when someone is logged in. Is it possible to change this in registry for example?

As in this post I am using a Thunderbolt Network Adapter and the device is not reachable, untill login. So I have no chance to log me in remotely...

Thank you for your support and your fast response.
