Description Amar Kumar Padhi 2006-06-02 02:56:50 EDT

Description of problem:
I was able to print on my Epson Stylus CX3200 printer till I applied some latest
updates for CUPS. Now it gives me the following error whenever I print or check
on the printer status.

[soam@amzone ~]$ lpstat -t
scheduler is running
system default destination: CX3200
device for CX3200: usb:/dev/usb/lp0
CX3200 accepting requests since Wed 31 May 2006 09:16:42 PM GST
printer CX3200 disabled since Wed 31 May 2006 09:16:42 PM GST -
        Unable to open USB device "usb:/dev/usb/lp0": Permission denied
[soam@amzone ~]$

On checking the permissions on lp0, no access is present. Giving complete
permissions does not help either. Moreover, the settings are lost once I reboot. 

[root@amzone dev]# ls -l lp*
crw-rw---- 1 root lp 6, 0 Jun  2 10:41 lp0


Version-Release number of selected component (if applicable):

[root@amzone dev]# ls -l lp*
crw-rw---- 1 root lp 6, 0 Jun  2 10:41 lp0

Comment 1 Tim Waugh 2006-06-02 04:02:40 EDT

What does 'ls -lZ /dev/usb/lp0' say? (You've shown me the permissions on /dev/lp0..)

Or perhaps this is the problem, that there is no /dev/usb/lp0?

Comment 2 Amar Kumar Padhi 2006-06-03 11:15:00 EDT

Yak, my mistake. Here is the output you requested - 

[root@amzone ~]# cd /dev/usb
[root@amzone usb]# ls -l
total 0
crw------- 1 soam root 180, 0 Jun  3 18:45 lp0
[root@amzone usb]# ls -lZ /dev/usb/lp0
crw-------  soam     root                                      /dev/usb/lp0
[root@amzone usb]#


One more important point I would like to share, I may be doubting the cups
upgrade, but in general I also did a kernel upgrade to 2.6.16-1.2111_FC5smp. I
am not sure, but I get a feeling that there may be some kind of permission locks
being enforced after this upgrade.

Thanks!

Comment 3 Tim Waugh 2006-06-04 07:33:54 EDT

What about these commands?:

/usr/sbin/getenforce
ls -lZ /usr/lib/cups/backend/usb

Comment 4 Amar Kumar Padhi 2006-06-05 10:03:08 EDT

[soam@amzone ~]$ su -
Password:
[root@amzone ~]# /usr/sbin/getenforce
Disabled
[root@amzone ~]# ls -lZ /usr/lib/cups/backend/usb
-rwx------  root     root                                     
/usr/lib/cups/backend/usb
[root@amzone ~]#

I again applied a kernel upgrade yesterday, but no change in printing error.

[root@amzone ~]# uname -a

Wait, I just spotted this:

That's because it's fixed. :-)
