Did you really see a message like this:

The USB device can perform faster if you connect it to a High Speed
USB 2.0 port?

Open Device Manager, by clicking Start, Run and in the box enter:

%SystemRoot%\system32\devmgmt.msc

Click OK.

Do you see any red Xs or yellow !s?

Expand the Universal Serial Bus controller section and look for the
words:

Enhanced Host Controller

Enhanced is the key word here which means high speed. If Enhanced is
not listed, it is just a USB 2.0, but not high speed but a USB driver
upgrade may just fix that (and usually does).

Occasionally there is a setting to change in the BIOS. In the BIOS
look for a section for USB, there may be an option for ECxx (Enhanced
Controller) that is disabled. Enable it, reboot.

If you are not sure about your BIOS or drivers maybe we can help you
find them:

Click Start, Run and in the box enter:

msinfo32

Click OK, and when the System Summary info appears, click Edit, Select
All, Copy and then paste
the information back here.

There will be some personal information (like System Name and User
Name), and whatever appears to
be private information to you, just delete from the pasted
information.

This will minimize back and forth Q&A and eliminate guesswork.

If one wants "high speed", Shenan is telling the OP to get a
USB2 (not an old USB).
