Since updating to KDE 4.11.4 my above scanner function has quite working with Sane backend applications. (xsane and aquireInages on openSUSE 12.3 and 13.1. Also a Brothers Brscan-Skey does not work. These all worked on KDE 4.11.3 and earlier.
The actually failure is an Error message saying "invalid Argument" Scamimage -L see the scanner: CODE: ---------- rpl7:~> scanimage -L device `brother4:bus3;dev6' is a Brother MFC-J6710DW USB scanner ---------- CODE ---------- linux-rpl7:~> lsusb Bus 003 Device 006: ID 04f9:0263 Brother Industries, Ltd ---------- CODE: ---------- rpl7:~> scanimage -T scanimage: rounded value of br-x from 297 to 296.973 scanimage: rounded value of br-y from 420 to 419.962 scanimage: sane_start: Invalid argument ---------- Originally I thought it was a failure in my MFC. But the application Skanlite works fine. Apparently the bad argument is the start command. When I use brscan-skey (scantofile) it is supposed to connect to the computer (USB connection, create a folder and then scan in the document. It does connect to the computer, and create the folder but it never starts the scanner. Starting xsane from the command. It starts, the GUI, header says: "xsane 0.998 MFC-J6710DW scanner" The error pops up: "Failed to start scanner: Invalid argument" This is what always worked before KDE latest update. There was an update to: libksane0-4.11.4-1.1.x86_64 as part of the kde update. /etc/udev/rules.d/55-libsane.rules CODE ---------- # Brother MFC-J6710DW ATTR{idVendor}=="04f9", ATTR{idProduct}=="0263", MODE="0664", GROUP="lp", ENV{libsane_matched}="yes" ---------- If you need any other info or tests, let me know. Meanwhile I keep looking. Ant ideas would be greatly appriciated.
