Hello All,
I lost USB-C connectivity after installing HP PC Hardware Diagnostics UEFI 8.2.0.0 (sp115284) and HP Notebook System BIOS Update F.20 (sp131763).Under Device Manager there a warning (Code 43) on UCM-UCSI ACPI Device.
I don't think this is OS related as I tried restoring an older backup and rolling back from Windows 11 to Windows 10 and the issue still persists.
I'm opening a new topic because the bellow topics didn't helped me.
