    Acer Nitro N50-640 USB not working.

    Hi.
    I have an Acer Nitro N50-640 that has been downgraded by fitting a Core i3-12100F processor and a Radeon RX560 graphics card. I am running Windows 11 Home.
    There are 6 USB ports on the back of the machine (2 blue, 4 black), and 1 red USB and a USB-C on the front of the machine. I believe that all of these are mounted directly on the motherboard.
    The red port on the front of the machine has stopped working whilst all the others are OK. I have tried eveything in software that I can think of, including uninstalling the USB Controllers in Device Manager and letting the PC re-install them on reboot.
    Nothing I have tried has had any effect, does this look like a hardware problem?
    Any ideas as to what to try next would be greatly appreciated.
    Thanks,
    Chris.

    The PCH controls all USB ports.
    It uses 2 firmwares, it is valid to do a complete update.

    Enter the equipment information, SNID, firmware backup...
