Most peripherals are nowadays connected to the PC via USB. The USB controller or USB host controller is responsible for organizing the USB ports.

If you have problems with USB devices on your PC, but Windows does not specifically point out the lack of a driver, the USB controller displays error messages like The driver detected a controller error on \Device\Harddisk1\DR1.

If you’re running Windows 10 and have problems with the USB controller or its drivers, this guide provides helpful solutions to solve the problem.

How can I fix The driver detected a controller error?

1. Check the hardware cables

1.1 If only one device is affected

  1. You might have a broken USB cable.
  2. Connect the device with a different USB cable.
  3. Try connecting the device to another computer/laptop or another USB port.
  4. If it doesn’t work here either, then the external device you’re trying to connect is having the issue.

1.2 If several USB devices no longer work correctly

  1. Shut down your PC and remove all the connected USB devices.
  2. Pull off the power plug and leave the PC completely without power for 60 seconds.
  3. Reconnect the power plug and then power up the PC.
  4. While in the Windows interface, reconnect the USB devices one by one, and try them out.
  5. If all the USB devices present the same problem, there may be a hardware defect in the device.
  6. But if this does not work, there might be a driver problem, or the corresponding drivers are simply missing.

It might not be about the cables or the devices themselves. Check our guide on what to do if your USB ports are not working.

2. Reset controller driver to zero

  1. Press the Windows + R key to open Run.
  2. Enter devmgmt.msc and press Enter or click OK.
  3. Once you are in the Device Manager, open the USB Controller category.
  4. The faulty controller should appear here with a yellow warning symbol. Right-click on it and click on Uninstall.
  5. If the uninstall option is not available, go to the Properties of the USB controller.
  6. Go to the Drivers tab and click on the Uninstall button.
  7. Restart your PC.

Windows should now search for a suitable USB driver and install it automatically.
