Abstract

This invention enables a USB 1.1 device and a USB 1.1 host to communicate seamlessly with a USB OTG device. The invention complies with both USB 1.1 and OTG specifications. The invention includes the USB 1.1 host, USB 1.1 device and mixed signal circuits to implement USB OTG functions. The mixed signal components are controlled by the USB 1.1 device microcontroller. The invention is a cost effective implementation compared to a custom ASIC design for USB OTG implementation.
