| 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 device has an USB port, either host, peripheral or | |
| dual-role. | |
| For an USB host port, 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>. | |

| Enable driver model for USB. The USB interface is then implemented | |
| by the USB uclass. Multiple USB controllers of different types | |
| (XHCI, EHCI) can be attached and used. The 'usb' command works as | |
| normal. OCHI is not supported at present. | |
| Much of the code is shared but with this option enabled the USB | |
| uclass takes care of device enumeration. USB devices can be | |
| declared with the U_BOOT_USB_DEVICE() macro and will be | |
| automatically probed when found on the bus. | |
