Bug Description

Binary package hint: cups

This bug report follows the question #99192 that seems without answer.

We are trying to connect a Xerox Phaser 6140 via usb to our Ubuntu Karmic 9.10 x86_64 linux box
(Linux 2.6.31-17-generic #54-Ubuntu SMP Thu Dec 10 17:01:44 UTC 2009 x86_64 GNU/Linux).
The cups version is: 1.4.1-5ubuntu2.1

The same printer works fine when connected via lan, but we need it working via usb ...
The same hardware works fine when booted as Windows XP.
I tried to apply the solution suggested by Garvinrick4 to the question #81362 (Brother HL-2140 USB printer not recognized in printer set up in Ubuntu 9.10 alpha 4), but it seems to give worse results, so I returned to the original state.
I suppose (may be I'm wrong) that the Garvin fixing has been already included in the current Karmic
Here is what I can see:

When we insert the usb connector, the /var/log/message records:

Jan 29 17:32:45 spvi-client3 kernel: [ 7152.187481] usb 2-1.7: new high speed USB device using ehci_hcd and address 5
Jan 29 17:32:45 spvi-client3 kernel: [ 7152.300670] usb 2-1.7: configuration #1 chosen from 1 choice

Jan 29 17:32:46 spvi-client3 kernel: [ 7153.331326] usb 2-1.7: usbfs: interface 0 claimed by usblp while 'usb' sets config #1

the command lsusb reports:
...
Bus 002 Device 005: ID 0924:3d65 Xerox
....

the command "lsmod | grep usb" gives:

usblp 15136 0
usbhid 43968 0

while in /var/log/cups/error_log we have:

E [29/Jan/2010:17:32:46 +0100] [cups-deviced] Bad line from "usb": direct usb://Xerox/Phaser%206140N "Xerox Phaser 6140N" "Xerox Phaser 6140N" "MFG:Xerox;CMD:PJL,RASTER,DOWNLOAD,PCLXL,PCL,HBPL,POSTSCRIPT;MDL:Phaser 6140N;DES:Xerox Phaser 6140N;CLS:PRINTER;STS:AAAQBAD/AP8AAAAAAAgAA2QDZANkA2QDZANkA2QDQBoAAAAAsIYAAAAAAAAAAAAA4AAAEAAAAAAQ

W [29/Jan/2010:17:32:46 +0100] [CGI] Unhandled message: interface=org.freedesktop.DBus.Introspectable, path=/, member=Introspect

reported twice.
I suppose that this means that cups can see that the new device has been attached and that it is able to try to understand how to handle it.
Looking at the error strings, I have seen that the bad lines were missing of their closing quote ".
Thus, I tried a substitute for the usb backend (/usr/lib/cups/backend/usb) that filtered the output of the real usb backend appending the missing closing quote.
This way, the execution of /usr/lib/cups/backend/usb gives the following output:

direct usb://Xerox/Phaser%206140N "Xerox Phaser 6140N" "Xerox Phaser 6140N" "MFG:Xerox;CMD:PJL,RASTER,DOWNLOAD,PCLXL,PCL,HBPL,POSTSCRIPT;MDL:Phaser 6140N;DES:Xerox Phaser 6140N;CLS:PRINTER;STS:AAAQBAD/AP8AAAAAAAgAA2QDZANkA2QDZANkA2QDQBoAAAAAsIYAAAAAAAAAAAAA4AAAEAAAAAAQ"
DA==;" """

Anyway, with this patch the problem is not solved, because in the error_log is still reported the following error:

W [29/Jan/2010:17:40:60 +0100] [CGI] Unhandled message: interface=org.freedesktop.DBus.Introspectable, path=/, member=Introspect

I haven't been able to understand what is the reason for this error, thus I returned to the original usb backend.

The result to the command "lpinfo -vv" is always the same (no matter if with the patch or not):
           direct scsi
           file cups-pdf:/
           network ipp
           network http
           network smb
           network beh
           direct hp
           network socket
           network lpd
           direct hpfax

          network lp

where you can see that the networked interface is well recognized while the "direct usb" is completely missing.

I the other log file (/var/log/cups/access_log) each "lpinfo -v" request records:

localhost - - [29/Jan/2010:17:59:17 +0100] "POST / HTTP/1.1" 401 75 CUPS-Get-Devices successful-ok
localhost - root [29/Jan/2010:17:59:17 +0100] "POST / HTTP/1.1" 200 2554 CUPS-Get-Devices -

Well.... Is there someone that can help me?
Thank you.

I reported basically, the same 'bug' on the KDE Bug Tracking System (https://bugs.kde.org/show_bug.cgi?id=214932). My Panasonic KX-P4410 printer, connected to one of my laptops USB ports in Kubuntu Karmic Koala 9.10 simply isn't recognized by CUPS, so I can't configure it. This same printer, same laptop, same USB port, in Kubuntu Jaunty 9.04 works just fine.

Can you run the follwoing command:

sudo /usr/lib/cups/backend/usb >out 2>err

and attach the files "out" and "err" to this bug report. Please attach the files separately, without compressing them.

No need to attach the outputs - running the command results in:

Just to confirm, this problem/bug remains in Kubuntu Lucid Lynx 10.04 32-bit which I installed this morning - a fresh installation from LiveCD burned last night. It is really a PITA not to have a functioning USB printer.

The segmentation fault observed by Paul L is also observed in bug 468701, but no fix for this one is proposed there. So please post the output of the commands shown in my previous comment.

Marking as duplicate ...
