    摘要： This is generally directed to systems and methods for control of two or more devices through a shared control bus. For example, the devices can be coupled to a host system through the control bus. In some embodiments, the devices can be configured by the host system through address select pins of the devices. For example, the host system can sequentially program each device to change its default address to a unique address. In some embodiments, an event can be propagated through each device, thus resulting in each device receiving the event at a different time. In some embodiments, configuration by the host system can include programming each device with a value representing its own position in the chain. In this case, a device can use this value to delay its response to the event, thereby allowing all the devices in the chain to respond to the event simultaneously.

    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.
