sane-find-scanner - find SCSI and USB scanners and their device files

.SH SYNOPSIS

.B sane-find-scanner
|
|
.RB [\-h|\-?]

.SH DESCRIPTION
|
|
.B sane-find-scanner
|
|
is a command-line tool to find SCSI and some USB scanners and determine their
|
|
Unix device files. It's part of the sane-backends package.
|
|
.PP
|
|
For
|
|
.B SCSI
|
|
scanners, it checks the default generic SCSI device files (e.g., /dev/sg0) and
|
|
/dev/scanner. The test is done by sending a SCSI inquiry command and looking
|
|
for a device type of "scanner" or "processor" (some old HP scanners seem to
|
|
send "processor"). So sane-find-scanner will find any SCSI scanner connected
|
|
to those default device files even if it isn't supported by any SANE backend.
|
|
.PP
|
|
For
|
|
.B USB
|
|
scanners, first the USB kernel scanner device files (e.g. /dev/usb/scanner0),
|
|
/dev/usb/scanner, and /dev/usbscanner are tested. The files are opened and the
|
|
vendor and device ids are determined if the operating system supports this
|
|
feature. Currently USB scanners are only found this way if they are supported
|
|
by the Linux scanner module or the FreeBSD or OpenBSD uscanner driver. After
|
|
that test, sane-find-scanner tries to scan for USB devices found by the USB
|
|
library libusb (if available). There is no special USB class for scanners, so
|
|
the heuristics used to distinguish scanners from other USB devices is not
|
|
perfect. sane-find-scanner will even find USB scanners, that are not supported
|
|
by any SANE backend.
|
|
.PP
|
|
sane-find-scanner won't find parallel
|
|
port scanners, or scanners connected to proprietary ports.

|
.SH OPTIONS
|
|
.TP 8
|
|
.B \-h, \-?
|
|
Prints a short usage message.
|
|
.TP 8
|
|
.B \-v
|
|
Verbose output. If used once, sane-find-scanner shows every device name and
|
|
the test result. If used twice, SCSI inquiry information and the USB device
|
|
descriptors are also printed.
|
|
.TP 8
|
|
.B \-q
|
|
Be quiet. Print only the devices, no comments.
|
|
.TP 8
|
|
.B \-f
|
|
Force opening all explicitely given devices as SCSI and USB devices. That's
|
|
useful if sane-find-scanner is wrong in determing the device type.
|
|
.TP 8
|
|
.B devname
|
|
Test device file "devname". No other devices are checked if devname is given.
|
|
.SH EXAMPLE
|
|
.B sane-find-scanner -v
|
|
.br
|
|
Check all SCSI and USB devices for available scanners and print a line for
|
|
every device file.
|
|
.PP
|
|
.B sane-find-scanner /dev/scanner
|
|
.br
|
|
Look for a (SCSI) scanner only at /dev/scanner and print the result.

|
.SH SUPPORTED PLATFORMS
|
|
USB support is limited to Linux (kernel, libusb), FreeBSD (kernel,
|
|
libusb), NetBSD (libusb), OpenBSD (kernel, libusb). Detecting the vendor and
|
|
device ids only works with Linux or libusb.
|
|
.PP
|
|
SCSI support is available on Irix, EMX, Linux, Next, AIX, Solaris, FreeBSD,
|
|
NetBSD, OpenBSD, and HP-UX.
|
|
|
|
.SH BUGS
|
|
No support for parallel port scanners yet.
