.SH DESCRIPTION
|
||||
.B 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.
|
||||
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.
|
||||
.PP
|
||||
For
|
||||
.B 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.
|
||||
scanners, it checks the default generic SCSI device files (e.g.,
|
||||
.IR /dev/sg0 )
|
||||
and
|
||||
.IR /dev/scanner .

.PP
|
||||
For
|
||||
.B 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.
