CONFIG_USB_MDC800
  Say Y here if you want to connect this type of still camera to
  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_HPUSBSCSI
  Say Y here if you want support for the HP 53xx series of scanners
  and the Minolta Scan Dual. This driver is experimental.
  The scanner will be accessible as a SCSI device.
  This can be compiled as a module, called hpusbscsi.o.

CONFIG_USB_MICROTEK
  Say Y here if you want support for the Microtek X6USB and
  possibly the Phantom 336CX, Phantom C6 and ScanMaker V6U(S)L.
  Support for anything but the X6 is experimental.
  Please report failures and successes.
  The scanner will appear as a scsi generic device to the rest
  of the system. Scsi support is required.
  This driver can be compiled as a module, called microtek.o.

CONFIG_USB_SCANNER
  Say Y here if you want to connect a USB scanner to your computer's
  USB port. Please read <file:Documentation/usb/scanner.txt> and
  <file:Documentation/usb/scanner-hp-sane.txt> for more information.

  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 scanner.o. If you want to compile it as
  a module, say M here and read <file:Documentation/modules.txt>.
