PS4: “Too Many USB Devices Connected” Fixed By Experts

One of the most common error messages PS4 users face is the one that says: “Too Many USB Devices Connected“. This error becomes so frustrating especially when there’s no USB device connected to the PS4. As a result, users don’t really know what to do in this situation but to restart the PS4 and try their luck again.

On the other hand, this error occurs when connecting a USB device that the PS4 system has conflicts with. Consequently, that leads the PS4 to freeze up and stop working.

Before trying to fix this error, lets learn more details about it.

Why Does This Error Occur?

too many usb devices connected to PS4 might cause this errorThe error message: “Too Many USB Devices Connected” on PS4 occurs due to several reasons:

  • An abrupt logical (programmatic) error within the PS4 system itself. This can be caused by a faulty game/application file, or simply, just some PS4 system files got corrupted. This situation happens to all systems, whether on computers or game consoles.
  • A sudden electric surge that negatively impacted the functionality of the PS4 USB ports. That results in the confusion of reading the signals coming from the PS4 USB ports causing the system to think there’re too many USB storage devices connected.
  • Using a USB hub with the PS4 and connecting too many USB devices to it.
  • Connecting a defective PS4 controller to the USB port, which sends corrupted signals to the system that can’t properly understand.
  • A defective PS4 USB port that generates electrical shorts once any USB device connects to it. Accordingly, the PS4 system will realize there’s an issue with the USB connection, therefore this error message appears.
  • A malfunctioning USB connector of the USB device might be a cause for this situation.

These are the most common reasons for this error. So, let’s learn now the suggested methods to fix it.

  1. Download the official PS4 firmware
    Head to your PC and download the latest system software from the PlayStation website. You’ll also need an external hard drive with a USB connection or a USB flash drive to transfer the update to your PS4. Grab an external hard drive or USB flash drive with about 1.1GB Mb of free space.
  2. Create a new folder on your USB device and name it PS4
    Inside that folder, create a folder and name it “UPDATE” in all caps. Save the firmware file into the “UPDATE” folder and you should be good to go. Make sure the file is named “PS4UPDATE.PUP” when you save it.

Now, restart the PS4 and check whether you still get the “Too many USB devices connected” error message or not.

Repair the Faulty Hardware

If nothing above works, most probably it’s a faulty hardware that causes the whole issue. You have to run several tests in order to figure out which one is it.

If no USB device is connected to the PS4 and you still get this error despite your attempts to fix it, it means the PS4 itself needs maintenance. It can be the USB port or even the motherboard. Only a technician can fix that for you.

If the error occurs only when you connect a USB device to the PS4, either the USB connector is defective, the USB device, or even the PS4 USB port. A savvy can discover the exact source of failure by doing varied tests on the PS4 and the USB devices.

Don’t forget to switch between the USB ports with the same USB device. Sometimes this works and it helps also knowing where the error comes from.


Error message: “Too Many USB Devices Connected” indicates that there’s something wrong going on with your PS4. You’ll be really lucky if one of the three methods above can resolve it. But if it’s a hardware issue, here you have to suffer.

In any case, if you have done your best to resolve this issue, yet it still persists, you must take your console to a technician.
