2 # USB Gadget support on a system involves
3 # (a) a peripheral controller, and
4 # (b) the gadget driver using it.
6 # NOTE: Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !!
8 # - Host systems (like PCs) need CONFIG_USB (with "A" jacks).
9 # - Peripherals (like PDAs) need CONFIG_USB_GADGET (with "B" jacks).
10 # - Some systems have both kinds of controllers.
12 # With help from a special transceiver and a "Mini-AB" jack, systems with
13 # both kinds of controller can also support "USB On-the-Go" (CONFIG_USB_OTG).
17 bool "USB Gadget Support"
21 USB is a master/slave protocol, organized with one master
22 host (such as a PC) controlling up to 127 peripheral devices.
23 The USB hardware is asymmetric, which makes it easier to set up:
24 you can't connect a "to-the-host" connector to a peripheral.
26 U-Boot can run in the host, or in the peripheral. In both cases
27 you need a low level bus controller driver, and some software
28 talking to it. Peripheral controllers are often discrete silicon,
29 or are integrated with the CPU in a microcontroller. The more
30 familiar host side controllers have names like "EHCI", "OHCI",
31 or "UHCI", and are usually integrated into southbridges on PC
34 Enable this configuration option if you want to run U-Boot inside
35 a USB peripheral device. Configure one hardware driver for your
36 peripheral/device side bus controller, and a "gadget driver" for
37 your peripheral protocol.

133 such as an AC adapter or batteries.
135 Enter the maximum power your device draws through USB, in
136 milliAmperes. The permitted range of values is 2 - 500 mA;
137 0 mA would be legal, but can make some hosts misbehave.

203 (U-Boot) and the host (remote device) that can be used just like any
204 other nework interface.
205 It will bind on the peripheral USB controller, ignoring the USB hosts
206 controllers in the system.
211 prompt "USB Ethernet Gadget Model"
212 default USB_ETH_RNDIS
214 There is several models (protocols) to implement Ethernet over USB
215 devices. The main ones are Microsoft's RNDIS and USB's CDC-Ethernet
216 (also called CDC-ECM). RNDIS is obviously compatible with Windows,
217 while CDC-ECM is not. Most other operating systems support both, so
218 if inter-operability is a concern, RNDIS is to be preferred.
221 bool "CDC-ECM Protocol"
223 CDC (Communications Device Class) is the standard for Ethernet over
224 USB devices. While there's several alternatives, the most widely used
225 protocol is ECM (Ethernet Control Model). However, compatibility with
226 Windows is not that great.
229 bool "RNDIS Protocol"
231 The RNDIS (Remote Network Driver Interface Specification) is a
232 Microsoft proprietary protocol to create an Ethernet device over USB.
233 Windows obviously supports it, as well as all the major operating
234 systems, so it's the best option for compatibility.
