Question about Dell OptiPlex 170L PC Desktop

1 Answer

Location of USB Root Hub

When plugging in an External Hard Drive on the lower front USB port, a message says "This USB device can perform faster if you connect it to a Hi-Speed USB 2.0 port". When I click on those available, it shows I have a USB Root Hub with 8 hi-speed ports. Where are they?

    Thanks for the quick reply. There are 4 USB on the back of my pc that I can readily see. All of them are full. The message says I have 8 hi-speed ports and I was just wondering if they are hidden somewhere or if I needed to add something or what!?

Hi dottyo,

Generally the front USB ports on a computer are USB version 1.1, good for USB keyboard and mouse or printer.

But, almost always the USB ports on the back of the pc are USB version 2.0 which is what you are looking for. Try any ports on the back of the pc case.

Hope that helps!
