    All of the USB ports on my Dell Precision M4800 are black, including all four of the SuperSpeed USB 3.0 ports. It all depends on how the manufacturer wants to do it. They are all labeled with the SS USB logo and give USB 3.0 transfer speeds.
    Initially all USB 3.0 ports were blue to easily distinguish them from USB 2.0 ports. Today, with the prevalence of USB 3.0, I guess black is back in now. I know all my motherboard's USB 3.0 ports are blue, where the two USB 2.0 ports are black. And this is a Z170 Skylake board. My USB 3.1 port is red. And I've one USB 3.0 white port, but the color denotes it's to be used for Q-Flash (BIOS updates).

    Anyway yeah, USB 3.0 ports (and 3.0 cable ends) are (usually) blue.

    Edit: BTW if you're using USB 2.0 cable on a 3.0 device, you're just getting 2.0 speeds. You need a 3.0 cable to get 3.0 speeds.

    That's interesting. That laptop is a 2013/2014 model.

    Well it's not totally improbable, but 99 percent USB 3.0 ports are going to be blue. And standard USB 3.0 cables are going to have blue ends. Google "3.0 ports" and check out the images. Google "USB 3.0 cables" and check those images

    If you do find a "true" USB 3.0 port that's fully black, it's more an anomaly than standard and the vendor just wanted to be "different"

    BTW does the owners manual for that laptop actually state those ports as USB 3.0??? If NOT, they're 2.0 ports.... even if they happen to say "High-Speed" USB. When 2.0 first came out, it was listed as "High-Speed" compared to USB 1.0
