Other Modules!

Serial and Ethernet are the easiest to get going but they are far from the only gadgets the Linux kernel supports. You can also try such options as:

  • Mass storage (you can have the Pi appear as a 'USB key' disk drive ) - note, we didn't get this up and running smoothly, it enumerated but disk access to the backing file didnt work on our windows machine
  • MIDI - shows up as a 'native' USB MIDI audio device
  • HID - appear to the host computer as a mouse/keyboard/joystick
  • Audio - Show up as an audio/speaker device & line in as well?
  • Composite - a mix of serial/ethernet/mass storage composite devices is available. Note that this may work on a Mac or Linux but for windows you'd need a custom driver
  • Printer, webcam, etc - There's about a dozen more options

For more details, check out the USB gadget API framework page

Sunxi also has a handy page

We compiled all of the available USB gadget modules into the December 25, 2015 (or later) kernel tgz. You can enable them by using modprobe or editing the /etc/modules file to enable. If they need options, creating a new file for those options in /etc/modprobe.d/usbgadget.conf or similar

In particular, here's the modules that are available:
