Disable a USB Port

Hi Eduardo

Disabling that USB Port, may also disable any ports beside it, do you have USB ports on another part of your PC?

Open Device Manager (accessible by right clicking your Start Button)

At the bottom of the device list, expand the 'Universal Serial Bus Controllers' section

How many devices have 'Hub' in the name, is there more than 1?

If so, right click one f those, then choose Properties and choose the Driver tab, is there an option to disable that there?

If that is the wrong hub, re-enable that and move to the next hub device, until you find the one for that USB port . . .
