Abstract
Systems and methods for specifying extended configuration descriptor information in a Universal Serial Bus (USB) device are described. In one aspect, an extended configuration descriptor is provided in firmware of a USB device. The extended configuration descriptor includes a set of non-standard class codes. Responsive to receiving a host-specific device request, the USB device communicates the extended configuration descriptor to a requestor.
