Your scanner is connected at USB "Bus 001" as "Device 005" and for the USB "Bus 01" the kernel "Driver=ehci-pci" is used which means so called "USB 2" is used for your scanner. For further information see my previous mail where I wrote: Regarding "USB 2" versus "USB 3" see also http://lists.alioth.debian.org/pipermail/sane-devel/2015-December/034197.html and http://lists.alioth.debian.org/pipermail/sane-devel/2015-December/034207.html In http://lists.alioth.debian.org/pipermail/sane-devel/2015-December/034207.html there is: ---------------------------------------------------------------- Scanners usually belong to the generic "Vendor Specific Class" because there is no specific USB device class "scanner". ---------------------------------------------------------------- In http://lists.alioth.debian.org/pipermail/sane-devel/2015-December/034197.html there is: ---------------------------------------------------------------- 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 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]
