Using sane(7) under OpenBSD
|
|
===========================
|
|
|
|
First read ${TRUEPREFIX}/share/doc/sane-backends/PROBLEMS.
|
|
|
|
USB
|
|
---
|
|
Since USB scanning will be handled by libusb, you need to allow the
|
|
_saned user access to the corresponding USB endpoint. To do so, find
|
|
where your scanner is attached to using dmesg(8) then change the
|
|
ownerships accordingly.
|
|
ugenX = /dev/ugenX
|
|
uhubX = /dev/usbX
|
|
|
|
e.g.
|
|
$ dmesg | grep ugen
|
|
ugen0 at uhub1 port 1 "EPSON USB MFP" rev 1.10/1.00 addr 2
|
|
$ sudo chgrp _saned /dev/ugen0.* /dev/usb1
|
|
|
|
The reason we are changing the group and not the user is that it will
|
|
allow for multi-function devices to work for both printing and scanning
|
|
(e.g. by being owned by _cups:_saned).
|
|
|
|
To preserve your changes after a system update, use rc.local(8).
|
|
e.g. for a multi-function printer/scanner add the following lines:
|
|
chown _cups:_saned /dev/ugen0.* /dev/usb1
|
|
|
|
You can then grant users direct access to the scanner by adding them to
|
|
the _saned group.
|
|
|
|
SCSI
|
|
----
|
|
SANE only supports the generic SCSI uk(4) devices.
|
|
Make sure your user account has access to the scanner device or you will
|
|
not be able to scan.
|
|
|
|
LOCKING
|
|
-------
|
|
Some backends (like sane-plustek(5)) use a lockfile for allowing
|
|
multiple access to one scanner. If using such a backend, you must
|
|
add yourself to the _saned group or you will not be able to scan.
|
|
|
|
NETWORK
|
|
-------
|
|
By default, the saned(8) daemon runs as _saned, so you need to allow the
|
|
_saned user access to the scanner device.
|
|
If you're planning on using the SANE network daemon (saned) with
|
|
inetd(8) as opposed to starting it standalone from the provided rc.d(8)
|
|
script, add the following line in /etc/services:
|
|
sane-port 6566/tcp saned # SANE network scanner daemon
