Samsung SCX-4200 scanner does not work on Ubuntu 8.04 Hardy Heron

[tayroni]

Summary: I have installed the samsung unified driver in gutsy and on hardy. The scanner works on gutsy but NOT on HARDY.

Description: I've installed the driver first using the script provided by samsung, and manually. The manual installation was done because that the script allows /etc read and write by users (I really want to know the name of the programmer who did this mess!)

In both ways: installation by script or manually, the driver for the printer and scanner works on a clean install of gutsy. The same don't happen for hardy: the printer works but the scanner is not recognized by xsane.

Output of sane-find-scanner (both Gutsy and Hardy). Using sudo scanimage -L, the scanner is found on gutsy, but not on hardy.

So, please, help me to figure out what's happening with the samsung scx-4200 scanner on hardy. Any help is welcome.


PS: To install the driver manually (best way), only for reference:

1) Download 20070720152943906_UnifiedLinuxDriver.tar.gz from samsung, extract the files, go to new directory cdroot and type these commands
cp Linux/noarch/at_root/etc/sane.d/smfp.conf /etc/sane.d/
cp -r Linux/noarch/at_opt/share/ppd/* /usr/share/ppd/custom/
cp Linux/i386/at_root/usr/lib/libmfp.so.1.0.1 /usr/lib/
cp Linux/i386/at_root/usr/lib/sane/libsane-smfp.so.1.0.1 /usr/lib/sane/
cp Linux/i386/at_root/usr/lib/cups/backend/mfp /usr/lib/cups/backend/
cp Linux/i386/at_root/usr/lib/cups/filter/* /usr/lib/cups/filter/
cd /usr/lib
ln -s libmfp.so.1.0.1 libmfp.so.1
ln -s libmfp.so.1.0.1 libmfp.so
cd sane
ln -s libsane-smfp.so.1.0.1 libsane-smfp.so.1
ln -s libsane-smfp.so.1.0.1 libsane-smfp.so

2) Edit /etc/sane.d/dll.conf and add the line "smfp" to the end of file. Add yourself to the groups lp and scanner.

3) Reboot

I DID IT!!!!! The SAMSUNG SCX-4200 now works on HARDY HERON!!!!!!

The problem was the driver software by SAMSUNG looks for the usb device on

/proc/bus/usb/00*/00*

and 8.04 drops support to /proc/bus/usb/00*/00* and port all software to look only on /dev/bus/usb/00*/00*

To reenable support on /proc/bus/usb I edited

/etc/init.d/mountdevsubfs.sh

and modify the lines

#
# Magic to make /proc/bus/usb work
#
#mkdir -p /dev/bus/usb/.usbfs
#domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
#ln -s .usbfs/devices /dev/bus/usb/devices
#mount --rbind /dev/bus/usb /proc/bus/usb

to

#
# Magic to make /proc/bus/usb work
#
mkdir -p /dev/bus/usb/.usbfs
domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
ln -s .usbfs/devices /dev/bus/usb/devices
mount --rbind /dev/bus/usb /proc/bus/usb

and reboot.

ONE CAVEAT: Using patched /usr/lib/libmfp.so.1.0.1 from http://jacobo.tarrio.org/Samsung_SCX-4200_on_Debian allows me to use xsane with normal user.

[sylvaticus]

Works like a shame! Thanks!

How to activate the "thanks" feature of this forum??

[roccivic]

Worked perfectly, thank you!

Rouslan

[jackbox]

How do you edit the LDP to /dev/usb.lp0 to use the modified libmfp.so.1.0.1 file so that the scanner works with a normal user?

[Benic]

Yeah ! Finally works ! Thanks

not sure if you want do; but I installed xp virtual machine and just used the scanner that way and just move doc over to shared folder. To get the usb devices to be seen in virtual machine via virtualbox I found this:

http://www.ubuntu-unleashed.com/2008/04/howto-install-virtualbox-in-hardy-heron.html

I already had virtual box installed so I skipped further down in the how to part once virtual box was already installed. I would like to use it inside my host os 8.04; but it says the patch for the scanner can make the system unstable. (not sure if that is true or not)

[unicko]

This is me problem:


# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.

# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.

# Your USB scanner was (probably) detected. It may or may not be supported by

But i can't use the scanner... please, help me.

Note: I use the driver software by samsung, i edited /etc/init.d/mountdevsubfs.sh and finaly use the this fix (http://jacobo.tarrio.org/Samsung_SCX-4200_on_Debian).

tell me what i doing wrong..???

[EckyBrazzz]

Hi,

I had the same problem, but resolved it in 8.10 x64

Solution :


sudo gedit /etc/fstab

and add after the last line


none /proc/bus/usb usbfs devgid=1000,devmode=664 0 0


Hope it helps someone

Regards,

EckyBrazzz

[tayroni]

I solved doing this:

The same manual for hardy cannot be followed by intrepid because
/etc/init.d/mountdevsubfs.sh was updated.

To reenable support on /proc/bus/usb/00*/00*, add yourself to the groups lp, lpadmin and scanner:

sudo adduser your_login_here lp
sudo adduser your_login_here lpadmin
sudo adduser your_login_here scanner

and edit the file /etc/init.d/mountdevsubfs.sh. ADD THE LINES:

#
# Magic to KEEP /proc/bus/usb working
#
mkdir -p /dev/bus/usb/.usbfs
domount usbfs "" /dev/bus/usb/.usbfs usbfs -obusmode=0700,devmode=0600,listmode=0644
ln -s .usbfs/devices /dev/bus/usb/devices
mount --rbind /dev/bus/usb /proc/bus/usb

right below the line

domount devpts "" /dev/pts devpts -onoexec,nosuid,gid=$TTYGRP,mode=$TTYMODE

Finally, reboot.
