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 Villarde113f292006-08-22 22:40:15 +020028 familiar host side controllers have names like "EHCI", "OHCI",
Linus Torvalds1da177e2005-04-16 15:20:36 -070029 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).

41 For more information, see <http://www.linux-usb.org/gadget> and
42 the kernel DocBook documentation for this API.

51 messages if you use this option to ask for those messages.
52
53 Avoid enabling these messages, even if you're actively
54 debugging such a driver. Many drivers will emit so many
55 messages that the driver timings are affected, which will
56 either create new failure modes or remove the one you're
