The error “device descriptor request failed” will be fixed.Allow the Arduino to load and open before proceeding.Restart your computer and plug the Arduino cable into the port.Unplug the power supply from your computer.

If the power supply is to blame for the failed USB device descriptor request, follow these steps to resolve the issue. This solution is somewhat unusual, but users attest to its effectiveness in resolving the Device descriptor request failed problem. It is likely that your Arduino is damaged, which can be inconvenient. Method-2: Check for Hardware IssuesĮven after putting the Arduino into various USB ports, it is clear that the issue is not with your port but with your Arduino. You should also test the Arduino on another computer to see whether it works there. If it fails, restart your computer and try again. If you receive the Unknown USB Device (Device Descriptor Request Failed) problem, connect the Arduino to a different port on your computer. Method-1: Connect the Arduino to Another Port Change your Arduino selective suspend setting.Run the hardware and device troubleshooter.Remove Arduino and scan for hardware changes.Uninstall the Arduino in the device manager.To solve this issue you can follow the methods below: Hence, you’ll see an error notice that says something like “Unknown USB Device (Device Descriptor Request Failed)” or “A Request for the USB Device Descriptor Failed.” When Windows cannot recognize a device or decide which driver to run, the iconic “Unknown USB Device (Device Descriptor Request Failed)” error occurs. The USB drivers are either corrupted or out of date.The USB device has been tampered with, corrupted, or infected with malware.You made errors when defining the USB driver settings.There was an error when you were replacing some PC components.Your most recent software upgrade encountered problems and corrupted the USB drivers.The following are the possible causes of this problem:

The “Unknown USB Device (Device Descriptor Request Failed) error message might be caused by hardware or system-specific problems. What Causes the Arduino Device Description Error A device descriptor file is typically a text file that contains unique identifiers for the device in which it is stored, such as a mobile phone.

It is a tiny file that is used to identify a device uniquely. A device descriptor, as the name suggests, is a file that describes the properties of a device.
