HP PCs - Troubleshooting USB Connections (Windows 10, 8)

This document applies to HP and Compaq computers with Windows 10 or Windows 8.
This document describes common errors and general troubleshooting tips for Universal Serial Bus (USB) devices, such as hubs, thumb drives, printers, and cameras.
Depending on your version of Windows, some graphics and information in this document might vary slightly.

Before you begin

Some USB devices, such as printers, scanners, and copiers require that the USB device software and drivers be installed before connecting the USB device to the computer. Always follow the installation documentation from the USB device manufacturer.
While troubleshooting the USB device, you might need to disconnect the USB device from the computer.
  caution:
Always follow manufacturer instructions for disconnecting USB devices from the computer. Some USB devices must be turned off and/or ejected before they are disconnected from the computer. Some other USB devices support the Windows Safely Remove Hardware feature.

Troubleshooting steps

Perform the following steps, as applicable, to troubleshoot USB devices that are not working correctly:
  1. Power: If the USB device operates on battery power, make sure the batteries are correctly seated and are functional. If the USB device operates on external power, make sure all the power connections are secure and the power cord is connected to a power source.
  2. Test the USB connection: Sometimes, simply disconnecting and reconnecting the USB device to the computer can solve the problem:
    1. Disconnect all USB devices from the computer except a USB mouse and keyboard (if in use). This includes hubs, thumb drives, printers, and cameras.
    2. With all USB devices disconnected, do one of the following:
      • If you have a desktop computer, connect the device that is not working correctly to one of the USB ports on the back of the computer (the ports attached directly to the motherboard).
      • If you have a notebook computer, connect the device that is not working correctly to a USB port on the notebook. Do not use a USB port replicator (such as a docking station or USB hub).
    What happens when the device is connected?
    • The device works correctly: The problem is most likely related to power or poor overall system performance.
      note:
      To prevent the USB device from failing in the future: Do not connect too many devices to the computer; wait 5 seconds after connecting a device before using it; use powered hubs to connect other devices; and do not attach USB devices when the system is busy (running slower than normal).
    • The device does not work: Leave the device connected and continue to the next step.
  3. Installing USB manufacturer software: Some USB devices require manufacturer software be installed before the USB device will work.
    1. If the USB device came with software, and it was not previously installed, install the software now, following the manufacturer instructions.
    2. After installing manufacturer software, reconnect the USB device that was having problems.
    The device should now work correctly. If problems persist, continue to the next step.
  4. Microsoft easy fix solutions: Microsoft provides a web-based automatic diagnostic and repair application. Go to the How to use Microsoft easy fix solutions webpage (in English) and select the troubleshooter that most closely matches your issue. Then follow the on-screen instructions. If the device still does not work, go to the next step.
  5. Windows Update: Running Windows Update checks for operating system updates required for your computer. Go to Windows Update (in English) and follow the on-screen steps to check for updates, and opt in on all recommended and optional driver updates. If the device still does not work, go to the next step.
  6. Microsoft System Restore: If the USB device was previously working, then subsequently became unusable, try Microsoft System Restore to go back to a time prior to when the device failed. Refer to Using Microsoft System Restore (Windows 10, 8) for more information. If the device still does not work, go to the next step.
  7. Device Manager: You might be able to troubleshoot the problem using the Device Manager.
    In Windows, search for and open Device Manager.
    Follow the instructions below, depending on how your device is listed in the Device Manager:
    • Unknown Device: A driver is not installed or was not set up correctly (Such as, when a USB device was removed while Windows was still setting it up as newly found hardware.). To correct this problem, uninstall and reinstall the driver for the device, as follows:

Front USB ports do not work on a desktop computer.

If your desktop computer came with USB ports on the front of the computer and they do not work, a cable inside the computer might have become disconnected. First, make sure the USB ports at the rear of the computer work by connecting a USB device to the rear port. If the device is not recognized in the rear port, then use the other sections in this document to resolve the problem. Use the following steps to see if the front USB ports have become disconnected from the motherboard:
  caution:
This product contains components that can be damaged by electrostatic discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (such as a conductive foam pad), and wear an ESD wrist strap connected to a grounded surface.
  1. Turn off the computer, disconnect the power cable, and position the computer so that you can easily work on it. If necessary, disconnect cables and move the computer to a table over a non-carpeted floor.
  2. Remove the side panel. If needed, you can find instructions that specifically match your computer by searching HP Customer Support (at the top of this page) using the model number of your computer and the term "opening the case".
    Figure : Removal of side panel (your computer might look different but is similar)
     Image of the side panel being removed.
  3. Look inside the computer. Wires coming from the USB PCA board at the front of the computer are routed to a set of USB pins on the motherboard. Make sure this connection is secure. If the wires are not connected or are partially connected, secure the wires to the proper USB connection on the motherboard.
    To find where the USB connector is located on the motherboard, look for 5 pairs of pins with a label that starts with USB, JUSB, FRONT_USB, or F_USB. If your motherboard has two sets of pins, FUSB1 and USB2 for example, use the lower number first. Also, you can refer to the motherboard specification that matches your specific model of computer. Find the motherboard specification from the HP Customer Support for your computer model.
