摘要：
A virtualized computer system includes at least one guest environment (guest), a service guest environment (SG) and trusted software. The at least one guest includes at least one driver having a first private message interface. The SG includes a first USB host controller (HC) driver, which is in communication with a USB HC. The first USB HC driver includes a second private message interface. The trusted software is in communication with the guest and the SG. The trusted software includes a data intercept/routing mechanism that facilitates secure communication between at least one USB device coupled to the USB HC and the guest using the first and second private message interfaces.
