Epson Perfection 1670 (Snapscan) isn't working, some kind of crash after first initialisation

[Andreas Ritter]

I have an Epson Perfection 1670, which worked with the snapscan - Module very good with older ubuntu releases.

In 14.04 there is a bug, which causes the following behaviour:

1. Connect scanner, sane-find-scanner recognize it and xsane find it, too.
2. Click on scan or even only on preview the scanner seems to initialize (moves shortly), after that nothing happens and after about 30 seconds a error message pops up, can't find scanner. (similar behavior with scanimage on terminal)
3. scanner could not found with xsane or sane-find-scanner.
4. Disconnect / Reconnect scanner from power -> begin with 1 again.

Installed packages:
dpkg -l |grep sane
ii libksane-data 4:4.13.0-0ubuntu1 all scanner library (data files)

Also does not work for me anymore ever since the update to 14.04. Have to reboot to Windows to use the device.

scanimage -L does list the device at first, it also is listed (always) doing an lsusb. Trying to use a scanning application (skanlite, xsane or vuescan) each app is not able to find the device and it does not show up any longer with scanimage -L but still under lsusb.

Status changed to 'Confirmed' because the bug affects multiple users.

[Dr. Juergen Helmers (juergen-helmers)]

I solved my problem by redownloading the firmware file which I had place in /etc/sane.d. The file that works for me :

fc6ef4674ffe8d2afa403f79cc8dbc0e esfw30.bin

Scanning works now.

Jürgen, thank you for the follow-up. Is there something that needs to be done to make this work automatically or can this ticket be closed?

[Rolf Leggewie (r0lf)]

Andreas, does this work for you now or is anything left to be done?

[Rolf Leggewie (r0lf)]

We'd like to figure out what's causing this bug for you, but we haven't heard back from you in a while. Could you please provide the requested information? Thanks!

Sorry for the late response. I don't have the scanner any more and I also switched to fedora, so I can't test any updates.
But in 2014, I know that I had the same firmware as Jürgen, so I don't think that was the problem there.
