When trying to start a Win10 VM, I was getting the following error.

Editing the VM did not present the device in question.

Saving and relaunching did not remove the orphan item and the error persisted. I had to manually remove the following block from the XML in order to launch the VM.

If it is not supposed to remove the orphan USB device, I recommend listing items in the XML but not attached to allow them to remain or be removed in the form editor.
