   4          Universal Serial Bus (USB) is a specification for a serial bus
   5          subsystem which offers higher speeds and more features than the
   6          traditional PC serial port.  The bus supplies power to peripherals
   7          and allows for hot swapping.  Up to 127 USB peripherals can be
   8          connected to a single USB host in a tree structure.
   9
  10          The USB host is the root of the tree, the peripherals are the
  11          leaves and the inner nodes are special USB devices called hubs.
  12          Most PCs now have USB host ports, used to connect peripherals
  13          such as scanners, keyboards, mice, modems, cameras, disks,
  14          flash memory, network links, and printers to the PC.
  15
  16          Say Y here if your device has an USB port, either host, peripheral or
  17          dual-role.
  18
  19          For an USB host port, you then need to say Y to at least one of the
  20          Host Controller Driver (HCD) options below.  Choose a USB 1.1
  21          controller, such as "UHCI HCD support" or "OHCI HCD support",
  22          and "EHCI HCD (USB 2.0) support" except for older systems that
  23          do not have USB 2.0 support.  It doesn't normally hurt to select
  24          them all if you are not certain.
  25
  26          If your system has a device-side USB port, used in the peripheral
  27          side of the USB protocol, see the "USB Gadget" framework instead.
  28
  29          After choosing your HCD, then select drivers for the USB peripherals
  30          you'll be using.  You may want to check out the information provided
  31          in <file:Documentation/usb/> and especially the links given in
  32          <file:Documentation/usb/usb-help.txt>.

  40          Enable driver model for USB. The USB interface is then implemented
  41          by the USB uclass. Multiple USB controllers of different types
  42          (XHCI, EHCI) can be attached and used. The 'usb' command works as
  43          normal. OCHI is not supported at present.
  44
  45          Much of the code is shared but with this option enabled the USB
  46          uclass takes care of device enumeration. USB devices can be
  47          declared with the U_BOOT_USB_DEVICE() macro and will be
  48          automatically probed when found on the bus.
