| 19 | USB is a master/slave protocol, organized with one master |
| 20 | host (such as a PC) controlling up to 127 peripheral devices. |
| 21 | The USB hardware is asymmetric, which makes it easier to set up: |
| 22 | you can't connect a "to-the-host" connector to a peripheral. |
| 23 | |
| 24 | Linux can run in the host, or in the peripheral. In both cases |
| 25 | you need a low level bus controller driver, and some software |
| 26 | talking to it. Peripheral controllers are often discrete silicon, |
| 27 | or are integrated with the CPU in a microcontroller. The more |
Jules Villard | e113f29 | 2006-08-22 22:40:15 +0200 | [diff] [blame] | 28 | familiar host side controllers have names like "EHCI", "OHCI", |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 29 | or "UHCI", and are usually integrated into southbridges on PC |
| 30 | motherboards. |
| 31 | |
| 32 | Enable this configuration option if you want to run Linux inside |
| 33 | a USB peripheral device. Configure one hardware driver for your |
| 34 | peripheral/device side bus controller, and a "gadget driver" for |
| 35 | your peripheral protocol. (If you use modular gadget drivers, |
| 36 | you may configure more than one.) |
| 37 | |
| 38 | If in doubt, say "N" and don't enable these drivers; most people |
| 39 | don't have this kind of hardware (except maybe inside Linux PDAs). |
| 40 | |
