Which ports are USB 1.0 and which are USb 2.0

I am looking into buying a portable external hard drive. These drives are usually USB-powered and require a USB 2.0 port to receive enough power.

I will want to connect the portable drive to the front USB ports on my computer (it is easier than reaching in the back every time). How can I tell if the 2 front USB ports on my HP desktop are USB 1.0 or USB 2.0?

The HP documentation specifies that the 4 USB ports in the back are USB 2.0 however it does not say what the 2 front USB ports are. Is there a way to tell?

is there also a way to tell how much power is supplied to each of the 2 front USB ports?

  1. If you will provide the model number of the HP I will try to help you find the answer.
  2. USB 2.0 came out in 2000. If your comp is not 10 to 12 years old, you have all 2.0 USB ports. Doubt you have USB 3.0 or your manual would say something about that.

    Hi, kenrivers. Thak you for offering to help.

    My HP model number is P6531C. It is a desktop.

    spooky2th: The computer was purchased in 2010. I know that I don't have USB 3.0. Also, not all my ports are USb 2.0. In the back of the computer are 4 USB 2.0 ports and 2 USB 1.0 ports.

    I just don't know what the 2 front USB ports are (1.0 or 2.0) and is one of those ports enough to power a portable hard drive without a separate power supply.
  4. Looking at the specs proved useless. The specs state that there are 2 USB ports on the front but don't specify whether they are USB 1.0 or 2.0. One way to test is to insert a USB 2.0 flash drive in one of the front ports and if you get a message something like "This USB device can perform faster if you connect it to a Hi-Speed USB 2.0 port" then you will know it is a USB 1.0 port.

    They weren't putting usb 1.0 out in computers in 2010. I'm sure you have usb 2.0 ports that are backwards compatible with usb 1.0 devices.

    Edit:
    Just found this link:

    Looks like there are two special USB ports for a mouse and keyboard and 4 usb 2.0 ports on the back panel.

    That particular model does in fact have USB 1.0 ports. It has 2 on the rear panel in addition to 4 USB 2.0 ports.
    You can disregard this now. I just saw your new post.
