    I just got a clevo P370em, and i had researched a lot beforhand.

    one thing i did not find out until 30min ago, was that i cannot boot from a usb 3 key, the boot manger will not see them.

    Just thought i would save some else the trouble ;)

    Right. USB 3 requires drivers, at least until it's natively supported by the BIOS. But it should detect it and run at USB 2 speeds.

    It depends on what you hook up to it as you will be limited to the lowest common denominator. Lets say you hook up a USB drive or memory card that transfers max 60Mb/s thats the fastest you'll go regardless of how fast the USB port is capable of doing. Even with USB 3.0 being 4.5Gb/s you'll never get that speed with most things you'll connect to it. Even the fastest consumer SSD which go 550MB/s (4.4Gb/s) wont saturate it. Unless you've hooking up something crazy fast through USB thats why you dont see those top speeds.
