Abstract
A method of improving USB device virtualization is proposed that allows giving virtual machines (VMs) direct access to USB devices with a combination hardware and software solutions. The USB host controller replaces device identifiers assigned by the VM with real device identifiers that are unique in the system. The real device identifiers are assigned by the virtual machine monitor (VMM) or the host controller.
