What is the cause of the “Last USB device not working” error

Before you go on to solve the problem, there are several possible causes for this error that you should be aware of first. It could be one of the following reasons:

Faulty ports: One of the most common reasons for this error is that the USB port itself is damaged or not working properly. If you’re getting this error after trying to connect a USB device to a specific port, it’s likely that the port is the issue. You can check if other USB devices work in that port. If they do, then the problem is with your USB device. If not, then the port itself is most likely damaged and you should have it checked by a professional.

Controller error: Another possible cause for this error is an issue with the controller. The controller is the chip that controls the USB ports on your computer. If it’s not working properly, it can cause problems with your USB devices. You can try updating your controller driver to see if that solves the problem.

Outdated controllers: As with any other driver on your computer, the controller driver can become outdated. This can cause problems with your USB devices. You should update your controller driver to see if that solves the problem.

Faulty or missing ports: This is another possible cause for the “USB Device Failed” error. If you’re missing a USB port or two, it can cause problems with your USB devices. You can try updating your controller driver to see if that solves the problem.

Although this error can be caused by a variety of circumstances, there are a few common solutions that you can try before calling a technician. The solutions presented here are free and work in most cases, so take the time to explore each solution. There is at least one that will help you.

  1. To do this, open the Device Manager and find the device you want to update.
  2. Right-click on the device and select “Update Driver.”
