Abstract
A system and method for emulating a USB peripheral device is disclosed. The system utilizes a USB programming and operating interface to interact with the host but formats the data into a format usable by a non-USB peripheral device. Such a system consumes less real estate and power than a USB interface controller and USB peripheral, but remains compatible with software designed to interact with those USB devices.
