	---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 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.

	  Value in milliseconds of the USB connection timeout, the max delay to

	  off and powered on in the usb hub driver.
	  This define allows to increase the HUB_DEBOUNCE_TIMEOUT default
	  value = 1s because some usb device needs around 1.5s to be initialized
	  and a 2s value should solve detection issue on problematic USB keys.
