USB OTG Add-on

smxUSBO is used with smxUSBD and smxUSBH to add USB On-The-Go (OTG) interconnectivity between portable devices. It adds APIs to switch the roles of a USB controller between USB host and USB device. These two roles cannot work simultaneously on the same controller. If your system has a host port and a device port and you want to use them simultaneously, you only need smxUSBH and smxUSBD.
