Thanks for your attention. I did a SSO login and opened this issue web page (1643544). Then did the command:
apport-collect 1643544 Package sane-backends not installed and no hook available, ignoring Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged. A window pops up "no further information gathered" (see attachment) $ sudo apt-get install sane-backends says that the package cannot be found. I cannot find it in synaptic either. And this page (https://launchpad.net/ubuntu/+source/sane-backends/1.0.25+git20150528-1ubuntu2) says, that it's for USB3 "or fast recent hardware" - which is not available at my system. So - what can I do now. ** Attachment added: "Bildschirmfoto von »2017-01-13 10-52-53«.jpg" https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1643544/+attachment/4803793/+files/Bildschirmfoto%20von%20%C2%BB2017-01-13%2010-52-53%C2%AB.jpg -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1643544 Title: HP Scanjet 7400c Scanner locks USB2 port Status in sane-backends package in Ubuntu: Incomplete Bug description: When trying to scan with the hp7400c (avision backend), the scanner will stop in the middle of the page, no further commands on a USB mouse or keyboard are possible. xsane will throw a I/O device error. This happens on my desktop with ubuntu 16.10 (Kernel 4.8.0-27) and my laptop (kernel 4.4.0-38) NO USB3 hardware is involved in my case, both machines have USB2-ports only, lsmod does NOT show and xhci modules loaded. I tried the command SANE_DEBUG_AVISION=8 SANE_DEBUG_SANEI_USB=5 scanimage > scanfehlerxx.txt and produced the files attached. The key statement might be: [sanei_usb] sanei_usb_read_bulk: trying to read 61054 bytes [sanei_usb] sanei_usb_read_bulk: read failed: No such device (it may have been disconnected) [avision] read 0 bytes [avision] No data arrived. This error occurs as well with Fedora 24, but NOT with debian 8.6. So it may be related with the more recent kernels and their behaviour on the USB ports.
