CONFIG_USB_AUERSWALD
  Say Y here if you want to connect an Auerswald USB ISDN Device
  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).
  The module will be called auerswald.o. If you want to compile it as
  a module, say M here and read <file:Documentation/modules.txt>.

CONFIG_USB_BRLVOYAGER
  Say Y here if you want to use the Voyager USB Braille display from
  Tieman. See <file:Documentation/usb/brlvger.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 brlvger.o. If you want to compile it as
  a module, say M here and read <file:Documentation/modules.txt>.

CONFIG_USB_EMI26
  This driver loads firmware to Emagic EMI 2|6 low latency USB
  Audio interface.

  After firmware load the device is handled with standard linux
  USB Audio driver.

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

CONFIG_USB_RIO500
  Say Y here if you want to connect a USB Rio500 mp3 player to your
  computer's USB port. Please read <file:Documentation/usb/rio.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 rio500.o. If you want to compile it as
  a module, say M here and read <file:Documentation/modules.txt>.

CONFIG_USB_TIGL
  If you own a Texas Instruments graphing calculator and use a 
  TI-GRAPH LINK USB cable (aka SilverLink), then you might be 
  interested in this driver.

  If you enable this driver, you will be able to communicate with
  your calculator through a set of device nodes under /dev.

  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 tiglusb.o. If you want to compile it as a
  module, say M here and read Documentation/modules.txt.

  If you don't know what the SilverLink cable is or what a Texas
  Instruments graphing calculator is, then you probably don't need this
  driver.

  If unsure, say N.

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>.
