I have a problem getting "invalid argument" from a Brother DCP-8155DN scanner that's working on Debian 7.6 (32-bit) but not Ubuntu 14.04 (64-bit). I tried changing from the USB 3.0 port to 2.0, but it didn't help.
The main thing I want to say here is that on someone's post, not sure if it's in this bug, they said maybe the problem had to do with the fact that lsusb and scanimage gave different dev and bus numbers. So I tried this on my computer where the scanner is working, where lsusb and scanimage gave different dev and bus numbers, too, so that's not the problem. For instance, lsusb: Bus 001 Device 005: ID 04f9:0293 Brother Industries, Ltd scanimage -L: device `brother4:bus4;dev1' is a Brother DCP-8155DN USB scanner Even though the bus and device numbers are different, scanimage -T starts up the scanner, and gscan2pdf works fine, produces a nice image. Also sane-find-scanner finds it: found USB scanner (vendor=0x04f9, product=0x0293) at libusb:001:005 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/478761 Title: failed to start scanner: Invalid argument To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xsane/+bug/478761/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
