    I'm trying to install ESXi 5.5 on a flash drive connected to the motherboard USB 3.0 header of my SuperMicro A1SAI-2558F motherboard. No matter what I seem to set in the BIOS, I can't get the ESXi installer to recognize the flash drive (I've tried two) in order to install ESXi onto it.

    I remember hearing about issues with USB 3.0 flash drives but is there also an issue with USB 3.0 headers? It's a real bummer if I can't use the internal header.

    P.S. The BIOS detects the flash drive just fine.

    A couple of things come to mind.

    * Try an external header and see if it works
    * What kind of pen drives are those?...some have some quirky driver issues
    * have you tried setting the usb ports in legacy mode?
    * Are there any unusual partitions on the flash drives?

    Yes, I was trying to do a Windows update for a friend and couldn't get it to work until I dropped to a USB 2.0 port. Sometimes it's the USB drivers that are loaded in the OS installer I think.

    Yea, just needed to plug into a USB 2.0 port to get it working. Sucks I can't use the on board USB 3.0 internal header.

    Are you out of USB headers internal? You can convert one of those to usb2 :)

    I'm sorry, I meant internal USB 3.0 port not header.

    Thanks. for the link. I actually have a USB header -> USB port adapter that I could use if I wanted. It's just that I have to remove my entire motherboard to get to everything as I have a very cramped case (U-NAS NSC-800)

    Did you try esx6? Perhaps USB 3 support is on that media

    I would but I only have a vSphere 5 license (need it for Veeam backups) and can't justify paying for a 6 license at this point for a home server.

    Thanks for the link. For now I'm working off a USB 2.0 port but next time I do maintenance on my server I'll give this a shot.
