(is it really "read the linux kernel > source"??) I've held a workshop on how to make your own USB device a few times. The material is available at http://cbs.stuge.se/ The workshop uses the 13 EUR LPC-P1343 microcontroller board from Olimex. The code also runs on any other LPC1343 board, but the buttons and LEDs used in the example might be missing then. LPC1343 is a very small Cortex-M3 microcontroller, not suitable for Linux and not comparable with the DaVinci SoC on the BeagleBone. My material will thus teach you nothing about how to implement a USB device using Linux on more powerful hardware, but it *will* show you a minimal working example of the most important USB primitives; control requests and interrupt transfers. I've also given a talk with an overview of USB basics. slides: https://events.ccc.de/congress/2010/Fahrplan/events/4234.en.html mp4: http://cdn.media.ccc.de/congress/2010/mp4-h264-HQ/27c3-4234-en-usb_and_libusb.mp4 webm: http://cdn.media.ccc.de/congress/2010/webm/27c3-4234-en-usb_and_libusb.webm html5: https://media.ccc.de/browse/congress/2010/27c3-4234-en-usb_and_libusb.html flash: https://youtu.be/uBBE2gihv5I Email me off-list if something is unclear. //Peter -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
