VirtualBox does support USB devices out of the box but requires an extension pack to enable USB 2.0 and USB 3.0 devices. If you see the ‘Failed to Attach the USB Device’ error every time you try to connect a USB device, don’t fret. We will list out the possible reasons why you see the error code along with multiple fixes to resolve the issue.

Now that we know what’s potentially causing the issue, let’s explore the fixes.
1. Restart VirtualBox
Before you move on to other advanced fixes, restart the VirtualBox application. If restarting the app doesn’t work, restart Windows. It will restart all the processes and services including the ones VirtualBox needs to function properly. Now, connect a USB device and attempt to attach it to a virtual machine in VirtualBox. If it still doesn’t show up, move to the next fix.
2. Check the USB Device on the Host System
Before trying to attach the USB device to the VirtualBox virtual machine, first check if it shows up on your host system. Launch the File Explorer and go to This PC and check if the USB drive appears there. If you don’t see the USB drive, do as follows:
If the USB port on your system malfunctions, the USB drive won’t show up in Device Manager or File Explorer. But if the USB drive doesn’t appear in the device manager even after changing the port, it could have a hardware malfunction. In that case, try connecting another USB drive to VirtualBox virtual machine.

3. Install the VirtualBox Extension Pack
