Pandaboard ES OMAP4460 USB Ports Technical Specifications Question Technical specifications for Pandaboard ES OMAP4460 shows that it has 3 USB ports.


1x USB 2.0 High-Speed On-the-go port
2x USB 2.0 High-Speed host ports


My question is that what's the difference between an On-the-go port and a host port?
Does a host port allow the Pandaboard to act as a slave when connected to a PC via USB?
Does a OTG port allow the Pandaboard to act as a slave when connected to a PC via USB?
I know nothing about 'Pandaboard'.  But a USB OTG port, acts as both Master &amp; Slave.  Depending on the spare pin of the mini usb cable (if its grounded or not). A Host port aka your PC can only talk to salves like Flash/Hard drives.  usb otg can talk to Flash drives &amp; also act like a Flash Drive too.
