[all variants] HP Scanjet 5100C / ppscsi in Hardy

[messelink]

Thanks a lot all for the good work!

Some small typos:

And you might need to change the group of the node in /dev to scanner. After you load the epst.ko you should do a "dmesg" to see to what node it is bound to. You should see something like [579138.038126] scsi 6:0:0:0: Attached scsi generic sg2 type 3, which means your scanner is at /dev/sg2. Then you do a sudo chown :scanner /dev/sg2 . I don't know if this is persistent after a reboot though...

Thanks messelink. I was obviously having a worse typing day than I thought. I've edited my post (again) to fix the remaining errors.

I've not had a chance to try this out yet - my scanner is not set up at the moment. Has anyone actually given it a go with the updated instructions who can confirm that it works?

[iadegesso]

hi there, I've found a solution for scanner ownership.

is not a permanent solution because it is lost on reboot. Also, while rebooting, the device name may change, so this scripting command is unhelpful.

You must write an appropriate udev rule in the file /etc/udev/rules.d/45-libsane.rules:

SUBSYSTEM=="scsi_generic",ATTRS{type}=="3", NAME="%k", SYMLINK="scanner%n", MODE="0777", GROUP="scanner"

A more detailed description can be found on my website at http://www.iadegesso.netsons.org/pps...pscsisoluzione in note 2.

First of all, however, do not forget to execute commands

For what it is worth I've verified that everything up to this point works in 9.04 except the last step provided by iadegesso, and that is only because I've not had to reboot my machine yet.

For those who love the step by step instructions or who have problems with anything so far let us know.. I'll keep on trying to help as long as I still have my scanner.

Hi guys,

I'm running ubuntu 9.04 and the instructions from haydnc worked well.
But for sane to find & detect my Scanjet 5100c I had to do a chmod 777 /dev/sg4.
Did someone tried the udev rule method with success with jaunty ?

And finally Great thanks to all the contributors of this post !

[haydnc]

I tested the solution provided by iadegesso successfully last night.

For those wanting the step by step:

gksudo gedit /etc/udev/rules.d/45-libsane.rules

Paste in the following:

SUBSYSTEM=="scsi_generic",ATTRS{type}=="3",NAME="%k",SYMLINK="scanner%n",MODE="0777",GROUP="scanner"

Save and exit the file.

Please note, as stated by iadegesso below this will only work if you've already followed the earlier instructions for adding a group called scanner then adding yourself to that group. There are instructions for doing this about 3 posts up.

The really interesting thing is that this could all change in a month when Karmic Koala is released. We know it works for Jaunty - if anyone is brave enough to install the beta when it lands later today and see if this still works we'd love to hear about it.

Otherwise things'll probably go back on hold until I've gotten 9.10 installed on my machine again.

[messelink]

If you are getting an error saying device not found when doing modprobe epst, before you try anythig else, make sure your scanner is plugged in...

Ahem... =P

Thanks for the good work guys, keep it up!

(No, I haven't tried Karmic yet but I'd love to hear if someone has)

[haydnc]

Depending on how organised I am I might be able to provide an answer to how well this works under Karmic next week (after the official release). Can't promise anything though as I'm rarely in a hugh rush to go through the upgrade process.

Hello everyone,
Thanks to this forum I have successfully got working my printer under Jounty, but there is a problem with Karmic release.
I haven't got time to wait for haydnc, so I tried it myself in Karmic.
Everything went well like in Jaunty, except this command:

When I type the command, it gets me empty line, like its processing something. When I try to close the terminal it says that there is a process running. Then after about 2 hours i get this message:

FATAL: Error inserting epst (/lib/modules/2.6.31-14-generic/kernel/drivers/parport/epst.ko): No such device

Any ideas what could be causing this?

Any help would be appreciated. : 7

[haydnc]

Well I can confirm that as Younio has said there is something not right with epst in karmic.

I've not been patient enough to leave the modprobe running so I don't know if I'm going to get the same error he has reported but I can confirm that I get the same blank line when running modprobe epst.

Running make definitely generates all the files that it should.

There is an 'error' during the build process (see code below) however once more I'm not enough of a programmer to work out if it's the cause of epst no longer working as it should.

For those programmers out there, who've been keen/brave enough to upgrade to karmic, the two errors above are lines 849 of ppscsi.c (the line in red):

#if LINUX_VERSION_CODE > KERNEL_VERSION(2,6,24)
cmd->sdb.table.nents = 0;
cmd->sdb.table.sgl = (char *) cmd->sense_buffer;
cmd->sdb.length = sizeof(cmd->sense_buffer);

and line 1192:

INIT_WORK(&pha->wq, ppsc_tq_int);

If anyone has any ideas on how to get this working again, please speak up.


Edit: Confirmed I get that same error message:

FATAL: Error inserting epst (/lib/modules/2.6.31-14-generic/kernel/drivers/parport/epst.ko): No such device

Anyone know why? Or anyone out there who found a work around?.
