NAME
sane-find-scanner - find SCSI and USB scanners and their
device filesSYNOPSIS
sane-find-scanner [-h|-?] [-v] [-q] [-p] [-f] [-F filename]
[devname]DESCRIPTION
sane-find-scanner is a command-line tool to find SCSI and
USB scanners and determine their Unix device files. Its pri-
mary aim is to make sure that scanners can be detected by SANE backends. For 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 seemto 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. For 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 thevendor and device ids are determined, if the operating sys-
tem 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 thattest, sane-find-scanner tries to scan for USB devices found
by the USB library libusb (if available). There is no spe-
cial USB class for scanners, so the heuristics used to dis-
tinguish scanners from other USB devices is not perfect.sane-find-scanner also tries to find out the type of USB
chip used in the scanner. If detected, it will be printedafter the vendor and product ids. sane-find-scanner will
even find USB scanners, that are not supported by any SANE backend.sane-find-scanner won't find most parallel port scanners, or
scanners connected to proprietary ports. Some parallel portscanners may be detected by sane-find-scanner -p. At the
time of writing this will only detect Mustek parallel port scanners. OPTIONS-h, -? Prints a short usage message.
-v Verbose output. If used once, sane-find-scanner
shows every device name and the test result. Ifsane-backends 1.0.19 Last change: 4 Oct 2004 1

used twice, SCSI inquiry information and the USB device descriptors are also printed.-q Be quiet. Print only the devices, no comments.
-p Probe parallel port scanners.
-f Force opening all explicitly given devices as SCSI
and USB devices. That's useful if sane-find-scanner
is wrong in determining the device type.-F filename
filename is a file that contains USB descriptors in the format of /proc/bus/usb/devices as used byLinux. sane-find-scanner tries to identify the
chipset(s) of all USB scanners found in such a file. This option is useful for developers when the output of "cat /proc/bus/usb/devices" is available but the scanner itself isn't. devname Test device file "devname". No other devices are checked if devname is given.EXAMPLE
sane-find-scanner -v
Check all SCSI and USB devices for available scanners and print a line for every device file.sane-find-scanner /dev/scanner
Look for a (SCSI) scanner only at /dev/scanner and print the result.sane-find-scanner -p
Probe for parallel port scanners.SEE ALSO

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. SCSI support is available on Irix, EMX, Linux, Next, AIX,Solaris, FreeBSD, NetBSD, OpenBSD, and HP-UX.

BUGS
No support for most parallel port scanners yet. Detection of USB chipsets is limited to a few chipsets.ATTRIBUTES
