       discover - hardware detection utility

       discover [options] [devices]

       discover is a command-line hardware detection utility.

       In  each  of  the following options, BUSES is a comma-separated list of
       bus types to probe, and DEVICES is a  blank-separated  list  of  device
       types.  The  following bus types are current recognized: pci, isa, pcm-
       cia, usb, ide, scsi, parallel, and serial.  The following device  types
       are  currently  recognized: bridge, cdrom, disk, ide, scsi, usb, ether-
       net, modem, sound, and video.  The word 'all' may be given as a  device
       type to specify each of the possible devices.

       -f FORMAT, --format=FORMAT
              Print results in the specified format.  The format string FORMAT
              is parsed in the style of a printf(3)  format  string,  with  %V
              expanding to the vendor name, %M expanding to the model name, %m
              expanding to the module name, %d expanding to  the  device  file
              path,  %S expanding to the name of the X server, %D expanding to
              the name of the X driver (for the XFree86 4.x X server), and  %i
              expanding to the device ID.  This option is useful for those who
              want to process the output of discover, since only  one  of  the
              vendor,  model,  module, device, xserver and xdriver options can
              be specified.  Do not forget that a '\n' must  be  specified  at
              the end of the format string if a trailing newline is desired.

              Enable detection of devices on the bus types BUSES.

              Enable detection of devices on all supported bus types.

              Disable detection of devices on the bus types BUSES.

              Disable detection of devices on all supported bus types.

              Print  the  vendor  name(s) of the devices (e.g., '3Com Corpora-

              Print the model name(s) of the devices (e.g.,  '3c905C-TX  [Fast

              Print the device path(s) of the devices (e.g., '/dev/hdc').

              Print the module name(s) of the devices (e.g., '3c59x').

              Print the X server name(s) of the devices (e.g., 'XFree86').

              Print the X driver name(s) of the devices (e.g., 'ati').

       -h, --help
              Show summary of options.

       -v, --version
              Show version of program.

       In  version  1.x  of  discover, there is no supported mechanism for the
       individual site administrator to add data about hardware that  discover
       does not already recognize.  The unsupported method is to edit the .lst
       files in /usr/share/discover, however this approach has obvious limita-
       tions as /usr may be a read-only mounted filesystem, and any upgrade of
       the discover-data package will overwrite the hardware list files unless
       special steps are taken by the administrator.

       It  is,  however,  possible  to  report  information to the authors for
       inclusion in a subsequent release of the  discover-data  package.   The
       Debian utilities bug(1) and reportbug(1) are the best ways to make such
       a report.  By far the most common requests are for unrecognized PCI and
       AGP  devices.   For such devices, please include the following informa-
       tion in your report:

       PCI vendor ID
              This information can be  retrieved  via  the  lspci(8)  utility.
              Take note of lspci's -n flag, which reports the numerical value.
              Both the numeric ID and the string (if available) are required.

       PCI model ID
              As PCI vendor ID, above.

       PCI device class
              As PCI vendor ID, above.

       name of corresponding kernel 2.4.26 module, if any
              This is the name of the kernel module you would load with, e.g.,
              modprobe(8)  to support the device.  If the device is a VGA-com-
              patible display controller (PCI class 0300), report the  XFree86
              server information instead (see below).

       name of X server binary, if any
              If  the device is a VGA-compatible display controller (PCI class
              0300), report the name of the XFree86 server used with  it.   In
              most cases, this is the XFree86(1) X server, but it could be one
              of the version 3.x X servers such as XF86_SVGA(1) or XF86_S3(1).

       name of X server driver module, if any
              If the device is a VGA-compatible display controller (PCI  class
              0300),  and  the  X server is XFree86(1), report the name of the
              video driver module used to drive the card, such as ati or nv.

       Finally, include any notes or remarks you have about the hardware.  The
       full  output  of  '/sbin/lspci' and '/sbin/lspci -n' is always appreci-
