Hallo, ich hab mir heute Ubuntu 18.04 installiert. Davor hatte ich den Drucker bereits unter Ubuntu 16.04 und 14.04 benutzt. Hier lief auch alles. Jetzt kann ich drucken, aber xsane mag den Scanner nicht erkennen. Ich habe wie zuvor alle Treiber von brother runtergeladen und laut deren Anleitung auch installiert. Weder unter root noch unter dem normalen user Account funktioniert der Scanner. Ich habe den Drucker unter usb angeschlossen.
sane-find-scanner ergibt das hier:
# sane-find-scanner will now attempt to detect your scanner. If the # result is different from what you expected, first make sure your # scanner is powered up and properly connected to your computer. # No SCSI scanners found. If you expected something different, make sure that # you have loaded a kernel SCSI driver for your SCSI adapter. could not fetch string descriptor: Pipe error found USB scanner (vendor=0x04f9 [Brother], product=0x0380 [DCP-J562DW]) at libusb:003:002 # Your USB scanner was (probably) detected.

Try scanimage -L and read the backend's manpage. # Not checking for parallel port scanners. # Most Scanners connected to the parallel port or other proprietary ports # can't be detected by this program.
Der gleiche Befehl ohne root Rechte ergibt das hier

unter lsusb wird mir der Drucker auch ganz normal angezeigt. Ich weiß leider nicht mehr weiter. Kann mir bitte jemand helfen?
