XSane and SANE do not maintain a proper connection with many Epson scanners

Same bug here, printing driver detects it fine so IMHO it's sane's problem.

There is a simple solution to this problem.
Just add the following line to the /etc/sane.d/epson.conf file at the bottom:
usb 0x4b8 0x838

I don't have the scanner to hand at the minute will test this over the week, but either way it still needs editing into sane config files if its something as silly as 1 line, it should be easy enough to code it in.

@alkemyst : did not work :(

You need to add:

usb 0x4b8 0x838

as alkemyst says but to:

/etc/sane.d/epson2.conf

Sorted.

The above did work, but I'm not sure this bug will be relevant for Lucid, I read somewhere that xsane is going to be removed in favour of something else?

Set Medium importance, Triaged, as there should be enough information here for a developer to know what to look at to enable this.

I apologize for the bug mail spam that you may have received due to my actions. I was recently working on bug 521827 when I found this report that seemed to describe the same behavior. I also found many other similar bugs about different Epson scanner models, but they are all related to the same package. I have marked them as duplicates in order to make this easier for any SANE developers who choose to look at this report.

Ok thank you very mush for your implication.
Just let me know if you have any news about that, ok?
Have a nice week-end.

Epson Stylus Scanner DX7400
Worked for me!
Thank you guys!

I'm having exactly the same problem with an Epson Perfection 3170 Photo. All worked on Karmic and earlier.

Meant to add that none of the above 'fixes' works for me.

Hi,
I just want to add, that also the communication via network regardless of autodetection is turned on or a fixed IP is used for the epson printer the initial communication works fine but gets interrupted with a I/O error.
The same has worked perfect with Ubuntu 8.04, which means this is a regression!

Thank you

It's still a bug for us, in Ubuntu 10.04 (10.04.2)

Unassigned from Canonical desktop t eam. We don't have this scanner, and unfortunately nobody of us is particularly experienced with such bugs, so I don't want to let this stay assigned forever, as this would give the wrong impression that it's being handled. I think this needs to be reported at and debugged with upstream (see http://www.sane-project.org/bugs.html). Thanks!

Hi,
I am not sure, but it looks like the sane-backend version 1.0.20 has some issue with the network implementation according to: http://comments.gmane.org/gmane.comp.graphics.scanning.sane.devel/16983
Since there is a new version available 1.0.22 would it be possible to provide this in an update?

Thank you

Christian
