The Linux kernel contains a complete subsystem for creating the device end of a USB connection. This means a capable embedded Linux system can look like a thumb drive, HID device, serial device, video device, audio device, or other type of device using a range of built-in drivers. It's also possible to create custom drivers for moving data to and from custom devices. This presentation and hands-on lab will describe some of the basics of USB and then describe how to create USB devices using the Linux gadget subsystem and communicate with them from a host using libusb.
