To solve "Windows has stopped this device because it has a problem" (Code 43), please try rebooting,
reinstating the device (in this case, ThunderboltEX 4), deleting other USB devices in device manager,
reinstalling the related driver, or updating the driver, and using Windows Update Troubleshooter to fix the problem.
Please test the above troubleshooting steps first, and if the problem still exists, please share the requested information below for us to better understand your scenario.
- the content of the setting in BIOS (or whether it is the default) and the OS build
- the brand and model name of the CPU, DRAM, GPU, and PSU currently installed
Thank you for the detailed information.
I have forwarded your case to the relevant department.
In order for the relevant department to further test your problem, could you also help confirm the brand and model of all the devices-
you will use Thunderbolt to connect to, as well as the current firmware version?
Could you help confirm if you have also updated the Intel Management Engine to the latest version, 188.8.131.520, before updating the BIOS?
Please refer to [Motherboard] IntelÃƒâ€šÃ‚Â® Management Engine Firmware Update Instructions(ME) > https://www.asus.com/support/FAQ/1047868
If the problem persists after the update, please provide an image of the BIOS main page, the ME firmware version.
I appreciate you confirming that the Intel Management Engine is now installed at the most recent version.
At present, I have reported your situation to the relevant department for verification.
In the meanwhile, may I inquire as to whether the ThunderboltEX 4 is placed in the PCIEX1 (G3) of the motherboard, which is the No. 3 port in the below-displayed image, and if the cable is connected to the TB_HEADER which is the No. 18 port?
If not, please remove any other devices that are occupying the ports before attempting to configure the connection with the manual.
