This probably falls in the category of a dumb question, but I haven't found too much from googling and I guess I'm not a USB expert.
I am curious about the capabilities of the Overo USB OTG port and what I can do with it in it's default configuration?
I have a tobi board here and when I connect some random device (like a simple usb->serial converter) to the USB-OTG port nothing is detected by the Overo. However, when I connect the USB-OTG port on the Tobi board to my desktop computer (linux) the desktop computer notices a new high speed usb device was just connected but can't identify it (still nothing noticed on the overo side.)
I found the "How to - usb" page on the wiki ... this claims that the USB OTG port is configured by default to act as a host ... that means I should be able to plug something in and see it, right? Or not right? Can I only connect things that are externally powered?
So how is this setup by default? What sorts of things can I expect to be able to do with the USB OTG port in the default configuration? The designers must have had some sort of usage cases in mind if they set it up a particular way?
