+	---help---
+	  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>.

+	  configure this Host Controller Driver.
+
+	  EHCI controllers are packaged with "companion" host controllers (OHCI
+	  or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
+	  will connect to EHCI if the device is high speed, otherwise they
+	  connect to a companion controller.  If you configure EHCI, you should
+	  probably configure the OHCI (for NEC and some other vendors) USB Host
+	  Controller Driver or UHCI (for Via motherboards) Host Controller
+	  Driver too.
