- help
- This host controller driver emulates USB, looping all data transfer
- requests back to a USB "gadget driver" in the same host. The host
- side is the master; the gadget side is the slave. Gadget drivers
- can be high, full, or low speed; and they have access to endpoints
- like those from NET2280, PXA2xx, or SA1100 hardware.
-
- This may help in some stages of creating a driver to embed in a
- Linux device, since it lets you debug several parts of the gadget
- driver without its hardware or drivers being involved.
-
- Since such a gadget side driver needs to interoperate with a host
- side Linux-USB device driver, this may help to debug both sides
- of a USB protocol stack.

- help
- USB is a master/slave protocol, organized with one master
- 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 DocBook documentation for this API.

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

- help
- Usually 2 buffers are enough to establish a good buffering
- pipeline. The number may be increased in order to compensate
- for a bursty VFS behaviour. For instance there may be CPU wake up
- latencies that makes the VFS to appear bursty in a system with
- an CPU on-demand governor. Especially if DMA is doing IO to
- offload the CPU. In this case the CPU will go into power
- save often and spin up occasionally to move data within VFS.
- If selecting USB_GADGET_DEBUG_FILES this value may be set by
- a module parameter as well.
- If unsure, say 2.

- A Linux "Gadget Driver" talks to the USB Peripheral Controller

- systems call these "client" drivers, of which "class drivers"
- are a subset (implementing a USB device class specification).
- A gadget driver implements one or more USB functions using

-
- Gadget drivers are hardware-neutral, or "platform independent",
- except that they sometimes must understand quirks or limitations
- of the particular controllers they work with. For example, when
- a controller doesn't support alternate configurations or provide
- enough of the right types of endpoints, the gadget driver might
- not be able work with that controller, or might need to implement
