| 51 | Universal Serial Bus (USB) is a specification for a serial bus |
| 52 | subsystem which offers higher speeds and more features than the |
| 53 | traditional PC serial port. The bus supplies power to peripherals |
| 54 | and allows for hot swapping. Up to 127 USB peripherals can be |
| 55 | connected to a single USB host in a tree structure. |
| 56 | |
| 57 | The USB host is the root of the tree, the peripherals are the |
| 58 | leaves and the inner nodes are special USB devices called hubs. |
| 59 | Most PCs now have USB host ports, used to connect peripherals |
| 60 | such as scanners, keyboards, mice, modems, cameras, disks, |
| 61 | flash memory, network links, and printers to the PC. |
| 62 | |
| 63 | Say Y here if your computer has a host-side USB port and you want |
| 64 | to use USB devices. You then need to say Y to at least one of the |
| 65 | Host Controller Driver (HCD) options below. Choose a USB 1.1 |
| 66 | controller, such as "UHCI HCD support" or "OHCI HCD support", |
| 67 | and "EHCI HCD (USB 2.0) support" except for older systems that |
| 68 | do not have USB 2.0 support. It doesn't normally hurt to select |
| 69 | them all if you are not certain. |
| 70 | |
| 71 | If your system has a device-side USB port, used in the peripheral |
| 72 | side of the USB protocol, see the "USB Gadget" framework instead. |
| 73 | |
| 74 | After choosing your HCD, then select drivers for the USB peripherals |
| 75 | you'll be using. You may want to check out the information provided |
| 76 | in <file:Documentation/usb/> and especially the links given in |
| 77 | <file:Documentation/usb/usb-help.rst>. |

| 80 | module will be called usbcore. |

| 87 | Many embedded system SOCs (e.g. freescale T2080) have both |
| 88 | PCI and USB modules with the USB module directly controlled by |
| 89 | registers and having no relationship to the PCI module. |
| 90 | |
| 91 | If you have such a device you may say N here and PCI related code |
| 92 | will not be built in the USB driver. |
