- 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, OHCI) can be attached and used. The 'usb' command works
- as normal.
- 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.
