cups backends don't recognize printer URI

[andschuster]

Binary package hint: cups

After upgrading from Intrepid to Jaunty Beta the automatic construction of the device URI works well:

root@darkstar:~# lpstat -v
Gerät für hp-LaserJet-1300: hp:/usb/hp_LaserJet_1300?serial=00CNBD032941
Gerät für PDF: cups-pdf:/

But the backends don't recognize the printer:

root@darkstar:~# lpinfo -v
network socket
network beh
file cups-pdf:/
direct hal
direct hpfax
direct hp
network http
network ipp
network lpd
direct scsi
serial serial:/dev/ttyS0?baud=115200
serial serial:/dev/ttyS1?baud=115200

Printing doesn't work. If I try to start printing nothing happens. The printer is listed:

Using the same printer with Intrepid installed on the same computer printing works well and the URI automatically constructed is the same reported by the backends.

Can you at first do a full system update? This should pull in CUPS 1.3.9-17.

If this still does not help, can you please post the output of

lsusb -vvv
ls -l /dev/bus/usb/*/*
ls -l /dev/usb/lp*

[andschuster (andreas-schuster2)]

I already did a full upgrade.

After rebooting "lpstat -v" gives the same listing as above, but "lpinfo -v" now shows (the difference to the situation above is that the printer was turned on during booting):

root@darkstar:~# lpinfo -v
network socket
network beh
file cups-pdf:/
direct hal:///org/freedesktop/Hal/devices/usb_device_3f0_1017_00CNBD032941_if0_printer_noserial
direct hpfax
direct hp
network http
network ipp
network lpd
direct scsi
serial serial:/dev/ttyS0?baud=115200
serial serial:/dev/ttyS1?baud=115200
network smb

That means that there are two different URIs.

I attached the output of "lsusb -vvv" as lsusbvvv.txt

Apparently I have a system experiencing the same cause, originally reported via bug #348316 "Printer (HWModel Name) May Not Be Connected".

The printer is connected to a remote hub. The remote hub is never connected during start-up for operational reasons.

Repeat of information posted to the other bug:

apt-cache policy cups
cups:
  Installed: 1.3.9-17
  Candidate: 1.3.9-17

I didn't try the PPA package or make any system changes.

The original issue was failure to connect via Bluetooth so I switched to
the USB cable expecting that would solve the problem, only to meet this
new one! The printer is automatically detected upon connection and
system-config-printer appears and offers a test-page print, which then
doesn't start, with the status reporting "Printer ... may not be
connected" whilst the job shows as "processing".

Monitoring udev whilst connecting *just* the printer directly to the PC shows the usb/lp* node being removed immediately after it is added. I've attached the full udevadm log, but here's the 'interesting' bit:

Do you need further informations?

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. Ubuntu 9.04 is no longer supported, it would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect -p cups 356142 and other relevant information.
