Hello,

Code: [Select]

device `plustek:libusb:004:002' is a Canon CanoScan N670U/N676U/LiDE20 flatbed scanner


Code: [Select]

found USB scanner (vendor=0x04a9 [Canon], product=0x220d [CanoScan], chip=LM9832/3) at libusb:004:002


Code: [Select]

Bus 004 Device 002: ID 04a9:220d Canon, Inc. CanoScan N670U/N676U/LiDE 20
as root its possible to run xsane but not as normal user so my question is how do i get information about the devices where my scanner is configured? ... well i think there is an permission problem thats why xsane didnt find any scanner if i launch it ..

Does there any command exists where i find out all the devices configured in my computer(in /dev)?

any suggestions would be appreciated

greetings raleeha

man sane usb
If sane-find-scanner finds your scanner only as root but not as normal user, the permissions for the device files are not
adjusted correctly.
http://www.linuxquestions.org/questions/linux-hardware-18/epson-n1240u-xsane-and-permissions-85191/

"It's also possible to mount the usbfs with the option "devmode=0666", e.g. by using the following line in /etc/fstab:
none /proc/bus/usb usbfs defaults,devmode=0666 00

:my /etc/fstab

scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages)
:as root

:/usr/share/doc/sane/README.linux
"So if scanimage -L lists your scanner as root but not as normal user
read on this text. Usually you must just add the users that are allowed to access
the scanner to group "scanner". The device files used by libusb are located in /proc/bus/usb/
(e.g. /proc/bus/usb/001/003) or in /dev/bus/usb/ (e.g. /dev/bus/usb/001/003), if
you use udev.  The exact file name can be found out by running sane-find-scanner
which would print "libusb:001:003" in this case.  While setting permissions with
e.g. "chmod a+rw /proc/bus/usb/001/003" works, this change is not permanent.
The permissions will be reset when the scanner is replugged or Linux is
rebooted."
"One solution to set permissions on-the-fly is Linux udev which comes with current distributions. SANE comes with a udev rules file in the tools/udev directory which may be used by distributions or can be copied to /etc/udev/rules.d manually."

Code: [Select]

ls -la /etc/udev/rules.d
total 16
drwxr-xr-x 2 root root 4096 Jul  1 17:16 ./

-rw-r--r-- 1 root root  442 Jul  1 14:21 70-persistent-net.rules

Has anyone experience in the change of files like in the udev tools directory?

[bigpaws]

All I need to do for my network scanner is add users to the scanner group.
Give it a try first.

hi,

do you know is ther eany gui tol to manage/admin users? becoz i did anything wrong when im changed groups from normal user..what i did: tried to add group scanner to normal user but after that it was all other groups deleted..well i think i need really know how to handle users and groups in vector linux.

Code: [Select]

Code: [Select]

id

I have a CanoScan (part of my MP160 multifunction printer). I can run it as user. I don't know if this will help, but in my Tuxcards file with Linux information I found this:
=====================
>lsusb reports the scanner as here: Bus 1 Device 4: ID 04a9:1714 Canon, Inc.

#chmod 777 /dev/bus/usb/001/004


I had to modify the command a bit because the directories on my system weren't quite what the command expected. By going to /dev/bus/usb/1 I discovered that the scanner was located at /dev/usbdev1.4. I located /dev/usbdev1.4 and changed the permissions so everyone could do everything.

After that, I was able to scan as user.
=======================

On my VL7 RC2 system I can start xsane as user and the Canon scanner comes up in xsane.

I couldn't get a consistent operation with xsane or the Canon scanner software, so I tried out VueScan and it did such a good job that I paid for it. No problems now with scanning.

I am having trouble getting the full picture.. You are running VL6? The scanner works fine when run as root?

Looks like you are running VL7 RC1, which has been superseded by RC2.
I suggest trying the newer version, and if problem persists, post a bug report for it.

[raleeha]

have download the vl7.0 rc2 live but y strange there already the problem as normal user i cannot login only root have access to scanner

[GrannyGeek]

I've reached the limits of what I can help you with. I don't know much about getting scanners to work for the user. Here I just flail about until it works and could never tell anyone what finally worked because I don't know myself. <g>

I'm having my own delightful scanner problem right now, as I'm trying to get my Epson Perfection V500 working under VL7 Standard RC2. I did have it working in VL6 SOHO on this same computer, but the notes I made have not worked in VL7 so far. I didn't try to install the scanner in the betas and RC1. I know it can be done but it's very confusing.

One bad thing about using VectorLinux or any distro that isn't RPM or DEB based is that it's very difficult to find instructions on the Web for doing anything. Everything is geared to Fedora/SuSE or Ubuntu. Supposedly "Linux is Linux," but in practice that isn't true because distros do their own thing in their own way.

Good luck with the scanner, and I hope someone who knows more than I do will jump in.
