Question ASUS ProArt B550-Creator - Thunderbolt 4 used as anything but USB 2.0 fails to detect ?

[Toilet_Jim]

Hello! I am running the ASUS ProArt B550-Creator without issue, except for when a USB 3 cable is plugged into either Thunderbolt 4 connector. The device fails to read and is instead not detected, using both gen 1 or 2 of 3.1, 3.2, or Thunderbolt certified cable, all yield the exact same results. However, if I plug a USB-C 2.0 connector into the port, the board detects the device and it runs just fine without any problems.

This has been tested in both Linux and Windows 10, using cables 1m or less with an AMD 5700G CPU. Running "lsusb" or Powershell equivalent "Get-PnpDevice -PresentOnly | Where-Object { $_.InstanceId -match '^USB' }" will not output any "Friendly Name" (on Powershell) to denote a device is detected in the slot.

BIOS version for your motherboard? While on Windows, do you see any component being flagged with a yellow exclamation in Device Manger? You've stated being on Windows 10, what version(not edition) are you on? uninstall the Thunderbolt drivers for your platform while on Windows and then manually reinstall in an elevated command, i.e, Right click installer>Run as Administrator.

Refer to page 35 of the bios manual. Verify that thunderbolt is enabled and if necessary go through all of the available thunderbolt options.
