[Bug 1532582] Re: Regression: SnapScan 1212U stuck after scanning one page
I've booted Ubuntu 14.04.5 from the LiveUSB prepared using: dd if=ubuntu-14.04.5-desktop-amd64.iso of=/dev/sdX bs=4M and couldn't reproduce the problem with my 1212U. In case of openSUSE a very similar problem has appeared to be caused by the tlp package (and its /usr/lib/udev/tlp-usb-udev bash script). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1532582 Title: Regression: SnapScan 1212U stuck after scanning one page To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1532582/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1532582] Re: Regression: SnapScan 1212U stuck after scanning one page
The workaround with a power management (keeping scanner turned on) is supposed
to be handled by a udev rule. If you check
/etc/udev/rules.d/
there should be a rule with something like:
ENV{libsane_matched}=="yes", RUN+="/bin/sh -c 'if test -e
/sys/$env{DEVPATH}/power/control; then echo on >
/sys/$env{DEVPATH}/power/control; elif test -e /sys/$env{DEVPATH}/power/level;
then echo on > /sys/$env{DEVPATH}/power/level; fi'"
I have a very similar problem with AGFA 1212u when using the latest openSUSE
releases:
https://bugzilla.opensuse.org/show_bug.cgi?id=1124909
In openSUSE case there is *something* that switches scanner's power
control from "on" back to the "auto" value.

dronus, thank you for reporting this and helping make Ubuntu better. To see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? ** Description changed: If I scan a page using the Agfa SnapScan 1212u, the scanner bar does not return to the edge but stops in the middle of the scanner at which point the scanner powers off. If one now tries to do another scan, the motor give a squeeking sound for some seconds without movement, and the software reports a connection failure. If the scanner USB connection is un- and replugged, the slit returns to it's home position and it works again.. for one scan. Some time ago, the scanner worked fine.

[Bug 1532582] Re: Regression: SnapScan 1212U stuck after scanning one page
The problem can be fixed by manually disabling USB autosuspend for the scanner by doing echo -1 >/sys/bus/usb/devices/USB_ADDRESS_OF_SCANNER/power/autosuspend as root. I guess an udev rule has to be added for that. However, the scanner would then power on while plugged all the time. So I guess it would be better if the sane backend would keep the device open until the scanner slit is retracted to it's home position, and then close it, allowing autosuspend power off the device. On the proprietary windows driver, the scanner is kept alive for some minutes until it is shut down. This is meant to keep the lamp warm which needs to be preheated after power off I guess. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1532582 Title: Regression: SnapScan 1212U stuck after scanning one page To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1532582/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
