<H2>DESCRIPTION</H2><PRE>
|
|
<B>sane-find-scanner</B> 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 <B>SCSI</B> scanners, it checks the default generic SCSI device files
|
|
(e.g., <I>/dev/sg0</I>) and <I>/dev/scanner</I>. The test is done by sending a SCSI
|
|
inquiry command and looking for a device type of "scanner" or "proces-
|
|
sor" (some old HP scanners seem to send "processor"). So
|
|
<B>sane-find-scanner</B> will find any SCSI scanner connected to those default
|
|
device files even if it isn't supported by any SANE backend.
|
|
|
|
For <B>USB</B> scanners, first the USB kernel scanner device files (e.g.
|
|
<I>/dev/usb/scanner0</I>, <I>/dev/usb/scanner</I>, and <I>/dev/usbscanner</I>) 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,
|
|
<B>sane-find-scanner</B> tries to scan for USB devices found by the USB
|
|
library libusb (if available). There is no special USB class for scan-
|
|
ners, so the heuristics used to distinguish scanners from other USB
|
|
devices is not perfect. <B>sane-find-scanner</B> 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. <B>sane-find-scanner</B> will even find USB
|
|
scanners, that are not supported by any SANE backend.
|
|
|
|
<B>sane-find-scanner</B> won't find most parallel port scanners, or scanners
|
|
connected to proprietary ports. Some <B>parallel</B> <B>port</B> scanners may be
|
|
detected by <I>sane-find-scanner</I> <I>-p</I> <I>.</I> At the time of writing this will
|
|
only detect Mustek parallel port scanners.

<H2>OPTIONS</H2><PRE>
|
|
<B>-?,</B> <B>-h,</B> <B>--help</B>
|
|
Prints a short usage message.
|
|
|
|
<B>-v</B> Verbose output. If used once, <B>sane-find-scanner</B> shows every
|
|
device name and the test result. If used twice, SCSI inquiry
|
|
information and the USB device descriptors are also printed.
|
|
|
|
<B>-q</B> Be quiet. Print only the devices, no comments.
|
|
|
|
<B>-p</B> Probe parallel port scanners.
|
|
|
|
<B>-f</B> Force opening all explicitly given devices as SCSI and USB
|
|
devices. That's useful if <B>sane-find-scanner</B> is wrong in deter-
|
|
mining the device type.
|
|
|
|
<B>-F</B> <B>filename</B>
|
|
filename is a file that contains USB descriptors in the format
|
|
of /proc/bus/usb/devices as used by Linux. <B>sane-find-scanner</B>
|
|
tries to identify the chipset(s) of all USB scanners found in
|
|
such a file. This option is useful for developers when the out-
|
|
put of <I>cat</I> <I>/proc/bus/usb/devices</I> is available but the scanner
|
|
itself isn't.
|
|
|
|
<B>devname</B> Test device file "devname". No other devices are checked if
|
|
devname is given.

|
|
<H2>EXAMPLE</H2><PRE>
|
|
<I>sane-find-scanner</I> <I>-v</I>
|
|
Check all SCSI and USB devices for available scanners and print a line
|
|
for every device file.
|
|
|
|
<I>sane-find-scanner</I> <I>/dev/scanner</I>
|
|
Look for a (SCSI) scanner only at /dev/scanner and print the result.
|
|
|
|
<I>sane-find-scanner</I> <I>-p</I>
|
|
Probe for parallel port scanners.

<H2>SUPPORTED PLATFORMS</H2><PRE>
|
|
USB support is limited to Linux (kernel, libusb), FreeBSD (kernel,
|
|
libusb), NetBSD (libusb), OpenBSD (kernel, libusb). Detecting the ven-
|
|
dor 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.
|
|
|
|
|
|
</PRE>
|
|
<H2>BUGS</H2><PRE>
|
|
No support for most parallel port scanners yet.
|
|
Detection of USB chipsets is limited to a few chipsets.
