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