USCANNER(4) BSD Kernel Interfaces Manual USCANNER(4)NAME
uscanner -- minimal USB support for scanners
SYNOPSIS
uscanner* at uhub?
DESCRIPTION
The uscanner driver provides minimal support for USB scanners. The driver recognizes a number of USB scanners, but to actually scan anything
there needs to be software that knows about the particular scanner. The SANE package provides support for some scanners.
HARDWARE
The uscanner driver works with the following scanners:
Epson
GT-7000
Perfection 610U
Perfection 636U
Perfection 1200U
Perfection 1200U Photo
Perfection 1260
Perfection 1660
Perfection 2400
HP
ScanJet 4100C
ScanJet 5200C
ScanJet 6300C
Many other scanners are recognized, but there is no software support for them yet.

HISTORY
The uscanner driver appeared in NetBSD 1.6.
BUGS
This driver should not really exist. The scanners it recognizes can be accessed through the ugen(4) driver instead. A proper scanner driver
would provide a uniform interface to scanners instead of exposing the innards of the scanner. The reason the driver exists is to have some-
thing that is compatible with the Linux driver.

sane-find-scanner - find SCSI and USB scanners and their device files
SYNOPSIS
sane-find-scanner [-h|-?] [-v] [-q] [-f] [devname]
DESCRIPTION
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.
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 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.
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 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.
sane-find-scanner won't find parallel port scanners, or scanners connected to proprietary ports.
OPTIONS -h, -? Prints a short usage message.
-v Verbose output. If used once, sane-find-scanner shows every device name and the test result. If used twice, SCSI inquiry informa-
tion and the USB device descriptors are also printed.
-q Be quiet. Print only the devices, no comments.
-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.
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.

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 parallel port scanners yet.
