No but if for instance you install usb wifi on one usb and then plug ur usb wifi into another usb port sys will detect new device and install software for it.

Your USB ports on your Dell computer are plug and play. If you have issues with your USB port, it is port related, driver related or device related. The following solutions will help you identify the problem to resolve your USB port issues.
To Identify a Working USB Port
Begin troubleshooting your USB ports by checking Device Manager to see if your USB ports or hubs are working properly.
  1. Click the Start button. ClickControl Panel.
  2. ClickSystem and Maintenance.
  3. ClickDevice Manager.
  4. Double-clickUniversal Serial Bus controllersand check to see if all your USB ports, hubs and controllers are functioning correctly. Any devices not functioning will have a yellow exclamation mark in front of them.
  5. If Device Manager shows any USB ports, hubs or controllers are not functioning, check for updated drivers.

To Update the USB Port Driver

An out-of-date BIOS driver can create issues with your system recognizing the USB port.
  • Watch a Video on Steps to Update Bios on Your Computer.
    1. When the update process is complete, your computer will restart again to load the operating system with the new driver version installed.

To Run a Diagnostic Test on your USB Port

Dell has an online diagnostic tool to help identify and fix issues with your system.
  1. Go to theDell PC Diagnosticpage
  2. UnderChoose a Diagnostic Type, selectHardware.

Computer won't recognize the store-it drive external hard drive


You may have a problem with your drive or the usb ports so we need to check both. The green light usually just means the device is getting power.

The first thing to do is unplug the drive and reboot the computer. Make sur eit has finished booting up completely. Then plug it into a different usb port NOT the same one. If it detects and works it was just the operating system or motherboard not recognizing whats called a legacy usb device.

Next we want to try a different usb device in the computer to make sure the ports are working.

And we want to try the drive in another computer to make sure it is working.

At this point you will know if the problem is your drive or the port. If it is the drive you can get it runnning again sometimes by taking the actual drive out an dputting it into a new external drive enclosure kit.
