This host controller driver emulates USB, looping all data transfer requests back to a USB 'gadget driver' in the same host. Select this only if your OMAP board has a Mini-AB connector. The initial role choice can be changed later, when two dual-role devices talk to each other. The most notable feature of USB OTG is support for a Dual-Role device, which can act as either a device or a host.

Say 'y' to link the driver statically, or 'm' to build a dynamically linked module called 'omap_udc' and force all gadget drivers to also be dynamically linked. This driver supports the controller in the OMAP 1611, and should work with controllers in other OMAP processors too, given minor tweaks.

Many Texas Instruments OMAP processors have flexible full speed USB device controllers, with support for up to 30 endpoints (plus endpoint zero).

Say 'y' to link the driver statically, or 'm' to build a dynamically linked module called 'goku_udc' and to force all gadget drivers to also be dynamically linked. The device controller has three configurable (bulk or interrupt) endpoints, plus endpoint zero (for control transfers). The Toshiba TC86C001 is a PCI device which includes controllers for full speed USB devices, IDE, I2C, SIO, plus a USB host (OHCI). If there's only one gadget driver, using only two bulk endpoints, don't waste memory for the other endpoints Say 'y' to link the driver statically, or 'm' to build a dynamically linked module called 'pxa2xx_udc' and force all gadget drivers to also be dynamically linked. It has fifteen fixed-function endpoints, as well as endpoint zero (for control transfers). The controller in the IXP 4xx series is register-compatible. Intel's PXA 25x series XScale ARM-5TE processors include an integrated full speed USB 1.1 device controller.

Say 'y' to link the driver statically, or 'm' to build a dynamically linked module called 'net2280' and force all gadget drivers to also be dynamically linked. It has six configurable endpoints, as well as endpoint zero (for control transfers) and several endpoints with dedicated functions.

NetChip 2280 is a PCI based USB peripheral controller which supports both full and high speed USB 2.0 data transfers. Many controller drivers are platform-specific these often need board-specific hooks. Systems should have only one such upstream link. If in doubt, or to conserve kernel memory, say 'N'.ДЄ USB device uses a controller to talk to its host. The information in these files may help when you're troubleshooting or bringing up a driver on a new board. Some of the drivers in the 'gadget' framework can expose debugging information in files such as /proc/driver/udc (for a peripheral controller). (on/off) ean Debugging information files.For more information, see and the kernel DocBook documentation for this API. (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). Configure one hardware driver for your peripheral/device side bus controller, and a 'gadget driver' for your peripheral protocol. Enable this configuration option if you want to run Linux inside a USB peripheral device.

The more familiar host side controllers have names like like 'EHCI', 'OHCI', or 'UHCI', and are usually integrated into southbridges on PC motherboards. Peripheral controllers are often discrete silicon, or are integrated with the CPU in a microcontroller.

In both cases you need a low level bus controller driver, and some software talking to it. Linux can run in the host, or in the peripheral. The USB hardware is asymmetric, which makes it easier to set up: you can't connect a 'to-the-host' connector to a peripheral.

(on/off/module) Support for USB Gadgets USB is a master/slave protocol, organized with one master host (such as a PC) controlling up to 127 peripheral devices.

With help from a special transceiver and a 'Mini-AB' jack, systems with both kinds of controller can also support 'USB On-the-Go' (CONFIG_USB_OTG). Some systems have both kinds of of controller. Peripherals (like PDAs) need CONFIG_USB_GADGET (with 'B' jacks). NOTE: Gadget support ** DOES NOT ** depend on host-side CONFIG_USBВ !! - Host systems (like PCs) need CONFIG_USB (with 'A' jacks). USB Gadget support on a system involves (a) a peripheral controller, and (b) the gadget driver using it. Howto configure the Linux kernel / drivers / usb / gadget
