2 | # USB Gadget support on a system involves | |
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). | |

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 | |
e113f29c | 28 | familiar host side controllers have names like "EHCI", "OHCI", |
1da177e4 LT |
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 | ||
41 | For more information, see <http://www.linux-usb.org/gadget> and | |
42 | the kernel DocBook documentation for this API. | |

812 | help | |
813 | The Printer Gadget channels data between the USB host and a | |
814 | userspace program driving the print engine. The user space | |
815 | program reads and writes the device file /dev/g_printer to | |
816 | receive or send printer data. It can use ioctl calls to | |
817 | the device file to get or set printer status. | |
818 | ||
819 | Say "y" to link the driver statically, or "m" to build a | |
820 | dynamically linked module called "g_printer". | |
821 | ||
822 | For more information, see Documentation/usb/gadget_printer.txt | |
823 | which includes sample code for accessing the device file. | |

829 | This driver provides two functions in one configuration: | |
830 | a CDC Ethernet (ECM) link, and a CDC ACM (serial port) link. | |
831 | ||
832 | This driver requires four bulk and two interrupt endpoints, | |
833 | plus the ability to handle altsettings. Not all peripheral | |
834 | controllers are that capable. | |
