New kernel -- no printer

[barryc]

My box has the following kernels installed:
2.6.33.7-pclos6.bfs (default)
2.6.37.2-pclos1.bfs
2.6.37.3-pclos1.bfs
2.6.37.4-pclos1.bfs
2.6.38.2-pclos1.bfs

fully updated kde4.6.2 (pass server)

My EPSON stylus photo R320 is installed and works perfectly ONLY with the default kernel.
All of the newer kernels allow installation of the printer, but none allow printing a test page or printing from any app.
I have tried everything in the following link http://www.pclinuxos.com/forum/index.php/topic,84526.0.html and none of the tips and exercises suggested solve this problem.

My udev rules do not contain the d/50-udev-default.rules mentioned by Tex in the above post.

I did try the changes to /etc/rc.d/rc.local: suggested by Tex and also a non-starter.  Am I missing the d/50-udev rules for some
reason?  ( I hate udev., as I know Tex does) Now I'm curious why I don't have this particular line in my udev rules.

Also , if there is something I missed as to why this printer won't install in any kernel after 2.6.33.7-pclos6.bfs.

The following are the files in my  /lib/udev/rules.d/  directory.

You should check what yours contains against the below list.

Code:

[user@Dell ~]$ cd /lib/udev/rules.d/
[user@Dell rules.d]$ ls

Ah, there they are.  I always thought they were located in /etc/udev/rules.d.
I have all of those on your list with the exception of 90-pulseaudio.rules.
I have removed and reinstalled about 10 times trying different kernels and
even with livecd of my install.  Only one that seems to work is the 2.6.33.7-pclos6.bfs kernel.
Any ideas?

can you post the ouput of the followin command ? I have an idea around usb device ...

lpstat -v

AS

[barryc]

[barry@BigBee ~]$ lpstat -v
device for EPSONSPhR320: usb:/dev/usb/lp0
[barry@BigBee ~]$

[AS]

[barry@BigBee ~]$ lpstat -v
device for EPSONSPhR320: usb:/dev/usb/lp0
[barry@BigBee ~]$

could you try to check existence and permission of such device (using new kernel) ?

ls -l /dev/usb/lp0

[barryc]

Code:

[barry@BigBee ~]$ lpstat -v
device for EPSONSPhR320: usb://EPSON/Stylus%20Photo%20R320
[barry@BigBee ~]$

lp0 permissions: rw,rw,0 User: root Group: lp

This is how it appears with new kernel (2.6.38.2-pclos1.bfs)
I will reboot and run the same code under 2.6.33.7-pclos6.bfs -- the working kernel
The name seems to have changed -- possibly reflecting the many reinstalls.

Here's everything after doing uname -a so I can keep the kernel versions straight.

Code:

[barry@BigBee ~]$ uname -a
Linux BigBee 2.6.38.2-pclos1.bfs #1 SMP PREEMPT Tue Mar 29 09:55:31 CDT 2011 i686 i686 i386 GNU/Linux
[barry@BigBee ~]$ ls -l /dev/usb/lp0
ls: cannot access /dev/usb/lp0: No such file or directory
[barry@BigBee ~]$

[barryc]

Code:

[barry@BigBee ~]$ lpstat -v
device for EPSONSPhR320: usb://EPSON/Stylus%20Photo%20R320
[barry@BigBee ~]$

Hmm. results identical to new kernel as far as device id is concerned.

lp0 permissions: rw,rw,0 User: lp Group: sys

This is how the permissions are under the default  kernel (2.6.33.7-pclos6.bfs)
Looks like the permissions are different in the two different kernels.
Now what??

Here's output with uname -a just to avoid any confusion:

Code:

[barry@BigBee ~]$ uname -a
Linux BigBee 2.6.33.7-pclos6.bfs #1 SMP PREEMPT Thu Oct 21 22:42:28 CDT 2010 i686 i686 i386 GNU/Linux
[barry@BigBee ~]$ ls -l /dev/usb/lp0
crw-rw---- 1 lp sys 180, 0 Apr  9 13:25 /dev/usb/lp0
[barry@BigBee ~]$

[barryc]

Okay, sorry for any confusion but now I see that I originally looked up permissions for
/dev/lp0 in Konqueror, but overlooked finding permissions for /dev/usb/lp0.

No such file found under the new kernel.
That could be why it can't print.  Any idea how to make the device available?

Appreciate your help greatly.

[AS]

resume, for clarity:

kernel 2.6.33.7:
device: /dev/usb/lp0
[barry@BigBee ~]$ lpstat -v
device for EPSONSPhR320: usb:/dev/usb/lp0
[barry@BigBee ~]$

the above configuration is congruent and fully working.

kernel 2.6.38.2:
/dev/usb/lp0: no such file or directory (I can replicate the same behavior on my system, I think this is due to module usblp not present in kernel 2.6.38.2)
[barry@BigBee ~]$ lpstat -v
device for EPSONSPhR320: usb://EPSON/Stylus%20Photo%20R320
[barry@BigBee ~]$

In kernel 2.6.38.2, I was not able to setup the my printer using control center -> printerdrake, but had to configure the printer using cups interface:
from a browser open http://localhost:631, go to administration -> add printer

you should see a list under "local printers", the last item being your Epson printer, choose that and continue  with the remaining configuration options.

Let us know if it work. (had worked for me, have done this from kernel 2.6.37.4-something, i.e. when usblp module disappeared).

Many thanks.  Yes, that is what I thought about the usblp module going away.
I am going to remove the current printer, reboot and try installing from cups.
I have done this before without success, but I can't remember exactly the exact
procedure that I followed.  I will post my results shortly.

[barryc]

Nope.  Nothing worked.  Finally, my install wouldn't complete booting.  I
may have cludged up something while editing stuff.  Anyway, I reinstalled
from a remaster I burned a week ago and everything is back to normal
with 2.6.33.7-pclos6.bfs kernel.  Printer works and I updated everything
on synaptic since the remaster was made.

I've spent enough time trying to finagle printing with the new kernel.  I think
there is a serious bug in it, probably the driver or the udev files.  I've had enough
udev for a while.  Maybe someone has a better solution.  I'll just stick with
my default kernel since all my hardware works fine with it.

The newest kernel (2.6.38.x) works fine and loads even faster but without
printing ability its a non-starter for me.

Thanks for your help, and I will be watching other posts re printing with this kernel.

You might try this - it worked for two of us. http://www.pclinuxos.com/forum/index.php/topic,88401.msg745358.html#msg745358
