ABSTRACT:
Methods, systems and apparatus may operate to send and receive universal serial bus (USB) control endpoint standard device requests with embedded functional sub-requests. From the USB device perspective, such operations may comprise receiving a control endpoint standard device request from a host at the USB device, decoding the functional sub-request forming a first portion of the control endpoint standard device request, decoding data forming a second portion of the control endpoint standard device request, and executing the functional sub-request by the USB device. Other methods, systems, and apparatus are disclosed.
