RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Joshua Rosen 2013-05-14 02:40:22 UTC 
Description of problem: The scanner on HP Officejets and Deskjets is not detected by sane after the 6.4 upgrade (I'm running Scientific Linux 6.4), it was fine from 6.0 to 6.3. I have an Officejet l7650, another system that I manage remotely has a Deskjet with the same problem. I tried replacing hplip with the latest from HP's website (hplip-3.13.4_rhel-6.0.x86_64.rpm), it didn't help. Printing works fine on both systems, it's strictly a scanner issue.


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


How reproducible:


Steps to Reproduce:
1. Bring up Simplescan of Xsane
2.
3.
  
Actual results: Scanner not detected


Expected results:

Comment 2 Nils Philippsen 2013-05-15 09:45:14 UTC 
I've changed the component to hplip as sane-backends hasn't seen an update since GA of RHEL6. The hplip maintainer should be able to tell you the changes made in the package between 6.3 (hplip-3.10.9-3.el6) and 6.4 (hplip-3.12.4-4.el6) and whether this can affect scanning on your device. Another possible error source could be (just speculating) changes in the kernel USB stack. Please check if your problems persists after downgrading alternatively either hplip (and libsane-hpaio) or the kernel packages, or both packages to the versions included in 6.3.
Comment 3 Joshua Rosen 2013-05-15 12:35:03 UTC 
I downgraded to 3.10 but the problem persists

hpijs-3.10.9-3.el6.x86_64.rpm  
hplip-common-3.10.9-3.el6.x86_64.rpm
hplip-3.10.9-3.el6.x86_64.rpm  
hplip-libs-3.10.9-3.el6.x86_64.rpm

Here is my lsusb output
Bus 003 Device 004: ID 03f0:2212 Hewlett-Packard OfficeJet Pro L7600
Comment 4 Joshua Rosen 2013-05-15 13:00:32 UTC 
It's not being detected in Fedora 19 alpha either. Looking back in Bugzilla it looks like I reported this problem in Fedora 17 so it was something that happened around then.

BTW the hardware is fine, the webscan function in the HP's web interface works.
Comment 5 Joshua Rosen 2013-05-15 21:32:38 UTC 
I did a clean install of 6.2. After the install Xsane and Simplescan worked fine. I updated the kernel, unfortunately kernel upgrades drag a lot of things with them one of which broke scanner detection. After the kernel update the scanner isn't detected by Xsane. It's not the kernel itself, I rebooted into the old kernel and it still doesn't work.
Comment 6 Joshua Rosen 2013-05-16 00:08:53 UTC 
I've been running some experiments. I did a clean install of SL 6.2. After the install the scanner was detected and functioned in Xsane and SimpleScan. I then updated the kernel which dragged along a number of other packages but not the hplip packages. After the upgrade the scanner wasn't detected any more. I then did a clean install of 6.3. Once again the scanner worked after the install. I did a couple of reboots and it still worked. I then updated the hplip packages, and only the hplip packages. The scanner was no longer detected by Xsane after the updates. I then downgraded the hplip packages to the original 6.3 packages. That didn't fix the problem, the scanner still isn't detected. I did a reboot and still no scanner.

I'm suspecting that it might be a udev file that's getting messed up.
Comment 7 Joshua Rosen 2013-05-16 00:45:25 UTC 
It looks like it is hplip or libsane-hpaio. When I downgraded to 3.10 it didn't install libsane-hpaio. When I installed libsane-hpaio and rebooted the scanner worked. Updating to 3.12 breaks it so that's where the problem is.

Is there anyway to post a bug do HP? I don't see any means of doing so on the hplip webpage.
Comment 8 Joshua Rosen 2013-05-16 01:17:32 UTC 
I removed hplip-3.12 from my 6.4 system and installed the 3.10 RPMS from 6.3,

hpijs-3.10.9-3.el6.x86_64.rpm  
hplip-common-3.10.9-3.el6.x86_64.rpm  
libsane-hpaio-3.10.9-3.el6.x86_64.rpm
hplip-3.10.9-3.el6.x86_64.rpm  
hplip-libs-3.10.9-3.el6.x86_64.rpm

Now the scanner works in 6.4.

Make sure you are able to reproduce the problem when you remove RHEL's packages and install latest hplip via their 'Automatic Installer'
(http://prdownloads.sourceforge.net/hplip/hplip-3.13.5.run)
before reporting it, because they'll tell you to do so anyway.
Comment 10 repomaint-rhbz 2013-05-16 08:46:41 UTC 
One SL 6.4 user with this problem managed to get his scanner detected by adding his unix user name to the 'lp' group in /etc/groups, see: http://scientificlinuxforum.org/index.php?showtopic=2292&view=findpost&p=15475

Maybe this piece of info helps in tracking down the bug.
Comment 11 Joshua Rosen 2013-05-16 13:36:15 UTC 
Adding my user name to the lp group fixed the problem. I first tried installing the latest version of hplip (hplip-3.13.5_rhel-6.0.x86_64.rpm) from the launchpad site. That fixed the problem but it wasn't the new code, it was because their RPM installs something that checks to see if a user is a member of the lp group and if not asks to add them to it. On a separate system I did a clean install of 6.4, the scanner didn't work with the default setup. However when I added my user name to the lp group, logged out and then logged back in, the scanner was detected.
Comment 12 Nils Philippsen 2013-05-17 09:57:55 UTC 
To me it seems that the device(s) in question aren't recognized by the udev rules as having a scanning function (and permissions aren't opened up to logged in users). By adding yourself to the "lp" group you get the direct access to the device file you need for scanning. Tim, what do you think?

This looks like a duplicate of bug #905143.
