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. SEE ALSO
scanimage(1), usb(4), usscanner(4) USB Scanners under Linux, 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. BSD

sane-find-scanner - find SCSI and USB scanners and their device files SYNOPSIS
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 primary 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 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 also tries to find out the type of USB chip used in the scanner. If detected, it will be printed after the vendor and product ids. sane-find-scanner will even find USB scan- ners, 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 port scanners 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. If used twice, SCSI inquiry informa- tion 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 by Linux. 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

Oliver Rauch, Henning Meier-Geinitz and others 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. 13 Jul 2008 sane-find-scanner(1)
