+         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>.

+       depends on USB && DM
+       help
+         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.
