CONFIG_USB_GADGET: USB Gadget Support

General informations

The Linux kernel configuration item CONFIG_USB_GADGET has multiple definitions:

USB Gadget Support found in drivers/usb/gadget/Kconfig

The configuration item CONFIG_USB_GADGET:

Help text

USB is a host/device protocol, organized with one host (such as a PC) controlling up to 127 peripheral devices. The USB hardware is asymmetric, which makes it easier to set up: you can't connect a "to-the-host" connector to a peripheral.

Linux can run in the host, or in the peripheral. In both cases you need a low level bus controller driver, and some software talking to it. Peripheral controllers are often discrete silicon, or are integrated with the CPU in a microcontroller. The more familiar host side controllers have names like "EHCI", "OHCI", or "UHCI", and are usually integrated into southbridges on PC motherboards.

Enable this configuration option if you want to run Linux inside a USB peripheral device. Configure one hardware driver for your peripheral/device side bus controller, and a "gadget driver" for your peripheral protocol. (If you use modular gadget drivers, you may configure more than one.)

If in doubt, say "N" and don't enable these drivers; most people don't have this kind of hardware (except maybe inside Linux PDAs).

For more information, see http://www.linux-usb.org/gadget and the kernel documentation for this API.
