The message is too big perhaps. I'll post again in small chuncks as soon as I have the chance. In the meanwhile a 16.04 user reported the scanner failure, apparently due to a libsane1 update. See https://forum.ubuntu-it.org/viewtopic.php?f=9&t=624458 page two, this is what he gets with sane-find-scanner
# 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 open USB device 0x1d6b/0x0002 at 002:001: Access denied (insufficient permissions) could not open USB device 0x1d6b/0x0001 at 006:001: Access denied (insufficient permissions) could not open USB device 0x1d6b/0x0001 at 005:001: Access denied (insufficient permissions) could not open USB device 0x04f2/0xb012 at 001:005: Access denied (insufficient permissions) found USB scanner (vendor=0x04f9 [Brother], product=0x01f5 [MFC-5490CN]) at libusb:001:004 could not open USB device 0x18d1/0x4ee7 at 001:003: Access denied (insufficient permissions) could not open USB device 0x1d6b/0x0002 at 001:001: Access denied (insufficient permissions) could not open USB device 0x1d6b/0x0001 at 004:001: Access denied (insufficient permissions) could not open USB device 0x1c4f/0x0003 at 003:003: Access denied (insufficient permissions) could not open USB device 0x1d6b/0x0001 at 003:001: Access denied (insufficient permissions) # Your USB scanner was (probably) detected.
