Could someone explain to me how to tell the MSG module which USB port to use and how to put this USB port in USB host/device mode to access the mass storage created by the module?

  • You actually have an USB root hub with multiple ports, where each port can get put into device mode? What kind of hardware are you talking about? All the OTG hardware I know has only a single "port" (which happens to be the root hub) that can be put into device mode. And you only see this on embedded systems. – dirkt Mar 11 at 18:14
