See http://en.opensuse.org/SDB:Configuring_Scanners in particular "Trouble-Shooting (Debugging)" but also "USB Cable Connection and Additional USB Hubs" and "USB Hardware + USB Kernel Modules + udev". Usually in case of "I/O error" trouble-shooting in the actual scanning software results nothing more than the already known "I/O error" so that you would have to do low-level USB trouble-shooting. Perhaps "dmesg" or /var/log/messages shows something of interest while the "I/O error" happpens for your USB scanner. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I narrowed it down to being in a libusb_set_configuration, and specifically in libusb/os/linux_usbfs.c:op_set_configuration an error from the ioctl(), but couldn't find any reason that it might come back with EPIPE (errno 32), that's never mentioned in the manpages. ..

I have faced the same kind of issues. Depending on kernel/hardware combination, I sometime meet the same libusb error. Compiling with libusb-1.0 solves it for me.

You can download sane-backends from the openSUSE build service at http://download.opensuse.org/repositories/home:/jsmeix/openSUSE_12.1/x86_64/ The packages in my "home:jsmeix" project are only for testing, without any guarantee or warranty, and without any support. As an extreme example, this means if your complete computer center crashes because of those packages, it is only your problem. On the other hand this does not mean that those packages are known to be terrible broken but they are not thoroughly tested so that any unexpected issue can happen. The package works for my Canon CanoScan N1240U/LiDE30 scanner but it also had worked all the time for me even with the libusb0 compatibility library (i.e. I cannot reproduce your libusb issue so that I cannot reproduce whether or not the new package avoids this particular libusb issue). If you like, please test it and provide feedback if it works for you or provide debug messages as above if it does not work for you. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
