    No, it's the other way around.  If an OTG peripheral is going to
    be compatible with anything, it's likely to be compatible with
    existing non-OTG peripherals like input devices and mass-storage
    devices.  The only reason for using OTG, after all, is the
    possibility of compatibility with extraordinarily low-cost
    peripherals.

    Yeah, ask your customer to explain to you why he needs On-The-Go
    compatibility... Or, hell, just ask him to explain what
    On-The-Go IS.  If he can't, you don't need it.
