... sometimes gives an I/O Error ...
In general "sometimes I/O Error" indicates that the root cause is somehow hardware related where "hardware" means the actual computer hardware plus the computer's built-in firmware (i.e. BIOS or UEFI) and "hardware related" means computer hardware plus firmware plus Linux kernel driver plus low-level hardware related software (e.g. libusb). You may have a look at "a stack consisting of various layers must be functional in its entirety" in https://en.opensuse.org/SDB:Configuring_Scanners#Basics You did not tell how your scanners are connected to your computer. If your scanners are connected via USB: There are currently issues with USB ports where the kernel module "xhci" is used as kernel driver. When "lsusb -t" shows "Driver=xhci_hcd" for the USB bus and port where the USB scanner is connected (see "lsusb" where the scanner is connected), then there could be issues depending on the computer hardware and firmware. In this case see https://bugzilla.opensuse.org/show_bug.cgi?id=856794 in particular see https://bugzilla.opensuse.org/show_bug.cgi?id=856794#c24 that reads (excerpt): ----------------------------------------------------------------- My machine has 4 USB ports, two labeled with the "super speed" USB logo (a.k.a. USB 3) and two labeled with the normal USB logo (a.k.a. USB 2) but for all 4 ports xhci is used and it fails on all 4 ports. ----------------------------------------------------------------- and see https://bugzilla.opensuse.org/show_bug.cgi?id=856794#c40 When your scanner is not connected at a USB port where the kernel module xhci_hcd is used as kernel driver (e.g. when your scanner is connected at a USB port where the kernel module uhci_hcd or ehci_hcd is used as kernel driver), then have a look at "Trouble-Shooting (Debugging)" in https://en.opensuse.org/SDB:Configuring_Scanners For example in your case to get USB debugging information you could use comands (as root) like ----------------------------------------------------------------- export SANE_DEBUG_SANEI_USB=128 scanimage -L unset SANE_DEBUG_SANEI_USB ----------------------------------------------------------------- Kind Regards Johannes Meixner -- SUSE LINUX GmbH - GF: Felix Imendoerffer, Jane Smithard, Graham Norton - HRB 21284 (AG Nuernberg) -- sane-devel mailing list: [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject "unsubscribe your_password" to [email protected]
