Failed to create a proxy device for the USB device Fix

Oracle VM VirtualBox, the virtual machine software, throws up the “Failed to create a proxy device for the USB device.” along with detailed information about the error code, USB information, etc. The main reason this fault occurs is that the host computer is already using the USB device that you are trying to plug in. As the host computer has the authority over the device, VirtualBox can’t create a proxy device in its place. Don’t worry. If you go through these solutions, the USB device will be up and running in no time at all.

1. On your host computer, click on the arrow sign on your taskbar.

2. Next, right-tap the USB ejector icon and tap the USB device that you want to remove from your system.
