Thanks for the files. That policy.out file doesn't look like it should, at all. It's supposed to contain a pile of additional rules that look like whatever the distribution's libsane package uses for USB devices. It appears that the Debian package maintainer split off the USB devices into a 20-sane.hwdb and only left the SCSI devices in 60-libsane.rules. This was done to address Debian bug 869244 (see [1]). [1]: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=869244 Unfortunately, that seems to have broken the logic in make-policy-file. That script has been working fine for more than a decade on multiple distributions but it looks like it needs some fixing up now. The Debian change will problably also affect *all* of Debian's downstreams :-/ > i have found that the problem clould be the xhci and suggest to change > the USB configuration, xhci pre-boot mode fron enabled to disabled, i > tried, but doesn't work > > and the scanner is connected to a usb 2.0 port Considering the above, I do not think xhci is involved. Even more so seeing you're using a USB 2.0 port.
