NAME
qscan - console tool for quality measurement of optical media SYNOPSIS
qscan [-l] [-h] qscan -d DEVICE [-S] [-i] [-m] qscan -d DEVICE [-p] [-r] [-w] [-v] qscan -d DEVICE [-f] [-s] [-t] [-v] qscan -d DEVICE -t wt [-s #] [-W] DESCRIPTION
qscan is the linux console tool for error correction measuring with optical devices. The related plugin allows to use vendor specific com- mands on your optical device. Currently supported vendors are Asus, Benq, Liteon, NEC, Pioneer and Plextor. For detailed information look at http://qpxtool.sourceforge.net/supported.html DEVICE
can be an IDE, SCSI, SATA, USB or FireWire connected optical drive. Not all SATA controller support all Plextor features.

NAME
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. 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 parallel port scanners yet. 15 Sep 2002 sane-find-scanner(1)
