Unfortunately those ports don't work. They have power, and produce dmesg output. But I can't mount any USB sticks on those ports.
All the USB 2 and 3 ports on the back panel work normally.
Any idea what is wrong? I did plenty of looking online but couldn't find many clues other than maybe a hardware fault. Or perhaps BIOS settings problem.[ 125.199551] usb 1-2: new high-speed USB device number 15 using xhci_hcd
