摘要： A USB host in one form comprises a plurality of endpoints and a state machine operable to queue user requests of multiple USB devices connectable to the host, host endpoints being dynamically allocated to corresponding endpoints of the USB devices. An exemplary method comprises, while a USB host is connected to multiple USB devices, allocating one or more host endpoints to corresponding endpoints on a USB device connected to the host; at least partially completing a user request between the one USB device and the USB host; re-allocating the host endpoints to corresponding endpoints of another USB device; and at least partially completing a user request between the other USB device and the host.
