    摘要: A method of guaranteeing a minimum sustained data transfer rate to a chosen device connected to a USB bus. A set of filter drivers are inserted in the driver stacks for at least two USB devices. These filter drivers are controlled by a filter driver controller that provides and receives information from the filter drivers. When a particular device needs a minimum sustained bandwidth for a transaction, the filter driver for that device notifies the filter driver controller. The filter driver controller then instructs the filter drivers for at least one other device to start interfering with USB transactions. This interference prevents the interfered with devices from using any of the USB bus bandwidth thereby providing a minimum sustained bandwidth to the non-interfered with device.
