Abstract
A USB function device ( ) for coupling to a USB host ( ). The USB function device ( ), comprises circuitry ( ) for providing a capability to the USB host, where the circuitry for the capability comprises an address space. The USB function device further comprises a USB interface circuit ( ) coupled between the USB host ( ) and the circuitry ( ) for providing a capability to the USB host. The USB interface circuit comprises a memory area ( ) comprising a code overlay endpoint ( ) accessible to the USB host for writing two or more code blocks to the code overlay endpoint. The USB interface circuit further comprises circuitry ( ) for communicating a first of the code blocks from the code overlay endpoint to the address space and for subsequently communicating a second of the code blocks from the code overlay endpoint to the address space. The circuitry for communicating is operable to communicate a code block from the code overlay endpoint to the address space after a start-up time of the USB function device.
