3 | # (a) a peripheral controller, and | |
4 | # (b) the gadget driver using it. | |
5 | # | |
6 | # NOTE: Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !! | |
7 | # | |
8 | # - Host systems (like PCs) need CONFIG_USB (with "A" jacks). | |
9 | # - Peripherals (like PDAs) need CONFIG_USB_GADGET (with "B" jacks). | |
cab00891 | 10 | # - Some systems have both kinds of controllers. |
1da177e4 LT |
11 | # |
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). | |

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 | |
e113f29c | 29 | familiar host side controllers have names like "EHCI", "OHCI", |
1da177e4 LT |
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). | |
41 | ||
42 | For more information, see <http://www.linux-usb.org/gadget> and | |
43 | the kernel DocBook documentation for this API. | |

123 | an CPU on-demand governor. Especially if DMA is doing IO to | |
124 | offload the CPU. In this case the CPU will go into power | |

838 | older versions of Windows. | |

844 | To make MS-Windows work with this, use Documentation/usb/linux.inf | |
845 | as the "driver info file". For versions of MS-Windows older than | |
846 | XP, you'll need to download drivers from Microsoft's website; a URL | |

856 | CDC EEM is a newer USB standard that is somewhat simpler than CDC ECM | |
857 | and therefore can be supported by more hardware. Technically ECM and | |
858 | EEM are designed for different applications. The ECM model extends | |
859 | the network interface to the target (e.g. a USB cable modem), and the | |
860 | EEM model is for mobile devices to communicate with hosts using | |
861 | ethernet over USB. For Linux gadgets, however, the interface with | |
862 | the host is the same (a usbX device), so the differences are minimal. | |
863 | ||
864 | If you say "y" here, the Ethernet gadget driver will use the EEM | |
865 | protocol rather than ECM. If unsure, say "n". | |
