    Hi all.

    I have a Supermicro X9SRA mainboard, that provides several USB 2.0 and USB 3.0 ports.
    After updating the bios to the latest available version, booting from a device connected to a USB 3.0 port is no longer possible. The USB 2.0 ports do still work normally.

    Since this board is EOL, I'd like to transfer the USB 3.0 part from the older to the newer bios.
    I can open both files with UEFITool, but I do not know which sections to transfer.
    Can anyone give me some advice?

    The bios files can be downloaded directly from supermicro's web site:
    old, with USB 3.0 boot: /support/resources/getfile.php?SoftwareItemID=2506
    new, without USB 3.0 boot: /support/resources/getfile.php?SoftwareItemID=3101
