| 20 | USB is a master/slave protocol, organized with one master |
| 21 | host (such as a PC) controlling up to 127 peripheral devices. |
| 22 | The USB hardware is asymmetric, which makes it easier to set up: |
| 23 | you can't connect a "to-the-host" connector to a peripheral. |
| 24 | |
| 25 | Linux can run in the host, or in the peripheral. In both cases |
| 26 | you need a low level bus controller driver, and some software |
| 27 | talking to it. Peripheral controllers are often discrete silicon, |
| 28 | or are integrated with the CPU in a microcontroller. The more |
Jules Villard | e113f29 | 2006-08-22 22:40:15 +0200 | [diff] [blame] | 29 | familiar host side controllers have names like "EHCI", "OHCI", |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 30 | or "UHCI", and are usually integrated into southbridges on PC |
| 31 | motherboards. |
| 32 | |
| 33 | Enable this configuration option if you want to run Linux inside |
| 34 | a USB peripheral device. Configure one hardware driver for your |
| 35 | peripheral/device side bus controller, and a "gadget driver" for |
| 36 | your peripheral protocol. (If you use modular gadget drivers, |
| 37 | you may configure more than one.) |
| 38 | |
| 39 | If in doubt, say "N" and don't enable these drivers; most people |
| 40 | don't have this kind of hardware (except maybe inside Linux PDAs). |

| 535 | Gadget Zero is a two-configuration device. It either sinks and |
| 536 | sources bulk data; or it loops back a configurable number of |
| 537 | transfers. It also implements control requests, for "chapter 9" |
| 538 | conformance. The driver needs only two bulk-capable endpoints, so |
| 539 | it can work on top of most device-side usb controllers. It's |
| 540 | useful for testing, and is also a working example showing how |
| 541 | USB "gadget drivers" can be written. |
| 542 | |
| 543 | Make this be the first driver you try using on top of any new |
| 544 | USB peripheral controller driver. Then you can use host-side |
| 545 | test software, like the "usbtest" driver, to put your hardware |
| 546 | and its driver through a basic set of functional tests. |
| 547 | |
| 548 | Gadget Zero also works with the host-side "usb-skeleton" driver, |
| 549 | and with many kinds of host-side test software. You may need |
| 550 | to tweak product and vendor IDs before host software knows about |
| 551 | this device, and arrange to select an appropriate configuration. |
| 552 | |
| 553 | Say "y" to link the driver statically, or "m" to build a |
| 554 | dynamically linked module called "g_zero". |

| 560 | You can configure this device to enumerate using the device |
| 561 | identifiers of the USB-OTG test device. That means that when |
| 562 | this gadget connects to another OTG device, with this one using |
| 563 | the "B-Peripheral" role, that device will use HNP to let this |
| 564 | one serve as the USB host instead (in the "B-Host" role). |

| 660 | EEM model is for mobile devices to communicate with hosts using |
| 661 | ethernet over USB. For Linux gadgets, however, the interface with |
| 662 | the host is the same (a usbX device), so the differences are minimal. |
