Public bug reported:
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

Jan 29 17:32:46 spvi-client3 kernel: [ 7153.331326] usb 2-1.7: usbfs: interface

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"

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

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

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:

CUPS-Get-Devices -
Well.... Is there someone that can help me?
Thank you.
