CONFIG_USB
  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 port in a tree structure.  The USB port is
  the root of the tree, the peripherals are the leaves and the inner
  nodes are special USB devices called hubs.  Many newer PC's have USB
  ports and newer peripherals such as scanners, keyboards, mice,
  modems, and printers support the USB protocol and can be connected
  to the PC via those ports.

  Say Y here if your computer has a USB port and you want to use USB
  devices.  You then need to say Y to at least one of "UHCI support"
  or "OHCI support" below (the type of interface that the USB hardware
  in your computer provides to the operating system) and then choose
  from among the drivers for USB peripherals.  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>.

  This code is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called usbcore.o.  If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_USB_DEBUG
  Say Y here if you want the USB core & hub drivers to produce a bunch
  of debug messages to the system log. Select this if you are having a
  problem with USB support and want to see more of what is going on.

CONFIG_USB_LONG_TIMEOUT
  This option makes the standard time out a bit longer.  Basically,
  some devices are just slow to respond, so this makes usb more
  patient.  There should be no harm in selecting this, but it is
  needed for some MGE Ellipse UPSes.

  If you have an MGE Ellipse UPS, or you see timeouts in HID
  transactions, say Y; otherwise say N.

CONFIG_USB_UHCI
  The Universal Host Controller Interface is a standard by Intel for
  accessing the USB hardware in the PC (which is also called the USB
  host controller). If your USB host controller conforms to this
  standard, you may want to say Y, but see below. All recent boards
  with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
  i810, i820) conform to this standard. Also all VIA PCI chipsets
  (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
  133).

  Currently there exist two drivers for UHCI host controllers: this
  one and the so-called JE driver, which you can get from
  "UHCI alternate (JE) support", below. You need only one.

  This code is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called usb-uhci.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_USB_UHCI_ALT
  The Universal Host Controller Interface is a standard by Intel for
  accessing the USB hardware in the PC (which is also called the USB
  host controller). If your USB host controller conforms to this

  with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
  i810, i820) conform to this standard. Also all VIA PCI chipsets
  (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
  133). If unsure, say Y.

  Currently there exist two drivers for UHCI host controllers: this
  so-called JE driver, and the one you get from "UHCI support", above.

  this standard, say Y. The USB host controllers on most non-Intel
  architectures and on several x86 compatibles with non-Intel chipsets
  -- like SiS (aktual 610, 610 and so on) or ALi (ALi IV, ALi V,
  Aladdin Pro..) -- conform to this standard.

  You may want to read <file:Documentation/usb/ohci.txt>.

  This driver is likely to work with most 10Mbps only USB Ethernet
  adapters, including some "no brand" devices. It does NOT work on
  SmartBridges smartNIC or on Belkin F5U111 devices - you should use
  the CATC NetMate driver for those. If you are not sure which one
  you need, select both, and the correct one should be selected for
  you.

  This driver makes the adapter appear as a normal Ethernet interface,
  typically on eth0, if it is the only ethernet device, or perhaps on
  eth1, if you have a PCI or ISA ethernet card installed.

  This code is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).

    CATC NetMate
    CATC NetMate II
    smartBridges smartNIC

  This driver makes the adapter appear as a normal Ethernet interface,
  typically on eth0, if it is the only ethernet device, or perhaps on
  eth1, if you have a PCI or ISA ethernet card installed.

  This code is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called catc.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_USB_DC2XX
  Say Y here if you want to connect this type of still camera to your
  computer's USB port.  See <file:Documentation/usb/dc2xx.txt> for
  more information; some non-Kodak cameras may also work with this
  driver, given application support (such as <http://www.gphoto.org/>).

  This code is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called dc2xx.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_USB_MDC800

  your computer's USB port. This driver can be used with gphoto 0.4.3
  and higher (look at <http://www.gphoto.org/>).
  To use it create a device node with "mknod /dev/mustek c 180 32" and
  configure it in your software.

  This code is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called mdc800.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_USB_STORAGE
  Say Y here if you want to connect USB mass storage devices to your
  computer's USB port.

  This code is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).

CONFIG_USB_USS720
  This driver is for USB parallel port adapters that use the Lucent
  Technologies USS-720 chip. These cables are plugged into your USB
  port and provide USB compatibility to peripherals designed with
  parallel port interfaces.

  The chip has two modes: automatic mode and manual mode. In automatic
  mode, it looks to the computer like a standard USB printer. Only
  printers may be connected to the USS-720 in this mode. The generic
  USB printer driver ("USB Printer support", above) may be used in
  that mode, and you can say N here if you want to use the chip only
  in this mode.

  Manual mode is not limited to printers, any parallel port
  device should work. This driver utilizes manual mode.
  Note however that some operations are three orders of magnitude
  slower than on a PCI/ISA Parallel Port, so timing critical
  applications might not work.

  Say Y here if you own an USS-720 USB->Parport cable and intend to
  connect anything other than a printer to it.

  This code is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called uss720.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_USB_DEVICEFS
  If you say Y here (and to "/proc file system support" in the "File
  systems section, above), you will get a file /proc/bus/usb/devices
  which lists the devices currently connected to your USB bus or
  busses, a file /proc/bus/usb/drivers which lists the USB kernel
  client drivers currently loaded, and for every connected device a
  file named  "/proc/bus/usb/xxx/yyy", where xxx is the bus number and
  yyy the device number; the latter files can be used by user space
  programs to talk directly to the device. These files are "virtual",
  meaning they are generated on the fly and not stored on the hard
  drive.

  You may need to mount the usbdevfs file system to see the files, use
   mount -t usbdevfs none /proc/bus/usb

  For the format of the various /proc/bus/usb/ files, please read
  <file:Documentation/usb/proc_usb_info.txt>.

  Please note that this code is completely unrelated to devfs, the
  "/dev file system support".

  Most users want to say Y here.

CONFIG_USB_BANDWIDTH
  If you say Y here, the USB subsystem enforces USB bandwidth
  allocation and will prevent some device opens from succeeding
  if they would cause USB bandwidth usage to go above 90% of
  the bus bandwidth.

  If you say N here, these conditions will cause warning messages
  about USB bandwidth usage to be logged and some devices or
  drivers may not work correctly.

CONFIG_USB_DABUSB
  A Digital Audio Broadcasting (DAB) Receiver for USB and Linux
  brought to you by the DAB-Team (<http://dab.in.tum.de/>).  This
  driver can be taken as an example for URB-based bulk, control, and
  isochronous transactions. URB's are explained in
  <file:Documentation/usb/URB.txt>.

  This code is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called dabusb.o.  If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_USB_USBNET
  This driver supports network links over USB with USB "Network"
  or "data transfer" cables, often used to network laptops to PCs.
  Such cables have chips from suppliers such as Belkin/eTEK, GeneSys
  (GeneLink), NetChip and Prolific. Intelligent USB devices could also
  use this approach to provide Internet access, using standard USB
  cabling. You can find these chips also on some motherboards with
  USB PC2PC support.

  These links will have names like "usb0", "usb1", etc.  They act
  like two-node Ethernets, so you can use 802.1d Ethernet Bridging
  (CONFIG_BRIDGE) to simplify your network routing.

  This code is also available as a kernel module (code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called usbnet.o. If you want to compile it as a
