Question about accessories

    Hello, I was looking through the documentation and I have a question about a sentence in the USB accessories section

    I cannot post a link, but it's in the android.dev.com guide/topics/connectivity/usb/accessory.htm

    "This allows Android-powered devices that cannot act as a USB host to still interact with USB hardware. When an Android-powered device is in USB accessory mode, the attached Android USB accessory acts as the host, provides power to the USB bus, and enumerates connected devices"

    I feel that I may be getting my terminology mixed up, but it seems like it's saying that a device that can't act as a host can be connected but then says that when connected the device will have to be the host. I am confused by how that is possible. I plan on connecting an Arduino Nano to a Nexus 7 tablet in order to read in information from the device.

    Thank you for any help.
