Question about Dell OptiPlex 170L PC Desktop

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!

You are using the correct connection, the external power supply is powering the drive, so the USB cable is just handling data. I believe the message may be telling you that you will get faster performance using a USB 2.0 connection, it is probably sensing that your computer's USB port is USB 1.1.

I hate this message.
You can use a program like PC Wizard from CPUID that will tell you what all of you pc specs are.

From your specs you may not have usb 2 ports.
Device manager should also say what usb ports you have.

The best ports to use are the ports on the rear of the computer, front usb ports sometimes dont have as much power to drive external hard drives or high drain devices

USB's slow and external drive


For the USB ports, you may want to verify that the drivers for the "enhanced USB" are up to date and for USB 2.0 or 1.1. USB 2.0 ports are generally backwards compatible for 1.1 devices. The "enhanced" does indicate USB 2.0 controller. 30mins to backup 3GB to your external drive is a VERY long time. USB 2.0 transfers data up to 480mbps, but if you get an error message indicating that the device can perform faster on a 2.0 port, you maybe transferring data at 12mbps which is USB 1.1 speed

To speed up the transferring of data, identify which USB contoller in Device Manager is the USB port you're having a problem with, and delete it from Device Manager. Then, plug in your external drive into a USB port its never used before.

As for the naming of hard drives, Hitachi partners with several drive manufacturers including Dell and IBM.

Ibm x22 doesnt recognise external DVD drive, keeps messaging saying could go faster on USB 2 port, but thats it


Did you check in the bios if your USB ports are configured as USB 2? That could fix it.
If not possible, try uninstalling the USB Root Hub devices in the device manager, that can fix some USB problems.

I replaced the USB adapter chord and know there's not enough power to run the drive. I think I need a DC adapter, 5V, 1A, that fits the drive.


If you get an error message "Insufficient power to operate USB device" when you plug in a USB device into the computer's USB port then this device is drawing power that the USB port can supply.
In case such as this, you need to purchased a powered USB hub and connect this hub into the computer's USB port and then connect the USB device into this powered USB hub.
