.SH DESCRIPTION
|
||||
.B sane-find-scanner
|
||||
is a command-line tool to find SCSI scanners and determine their Unix device
|
||||
files. It's part of the sane-backends package. It checks the default generic
|
||||
SCSI devices, e.g. /dev/sg? for Linux. Also /dev/scanner is checked. 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 even if it isn't supported by any
|
||||
SANE backend. It won't find parallel port, USB, or other non-SCSI scanners.
|
||||
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. It checks the
|
||||
default generic SCSI devices, e.g. /dev/sg? for Linux and the their USB
|
||||
pendants (e.g. /dev/usb/scanner0). Also /dev/scanner and /dev/usb/scanner are
|
||||
checked. 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 even if it isn't
|
||||
supported by any SANE backend. For USB devices, the corresponding files are
|
||||
opened and the vendor and device ids are determined if the operating system
|
||||
supports this feature. Currently USB scanners are only found if they are
|
||||
supported by the Linux scanner module (or a similar system on other
|
||||
platforms). sane-find-scanner won't find parallel port scanners, or scanners
|
||||
connected to proprietary ports.

No support for non-SCSI scanners yet.

No support for parallel port scanners yet. USB support should be extended to

other platforms and scanners.
