udevadm test /devices/pci0000:00/0000:00:1d.7/usb2/2-4'
shows:
'Invalid rule /etc/udev/rules.d/60-brother-libsane-type1.rules:17:
unknown key 'SYSFS{idVendor}'
So consequently your device is configured as printer-only:
RUN '/lib/udev/tlp-usb-udev %p' /lib/udev/rules.d/85-tlp.rules:10
handling device node '/dev/bus/usb/002/003', devnum=c189:130, mode=0664, uid=0,
gid=7
preserve permissions /dev/bus/usb/002/003, 020664, uid=0, gid=7
preserve already existing symlink '/dev/char/189:130' to '../bus/usb/002/003'

Title:
Many 3rd party scanner drivers are broken by a sane change
Status in sane-backends package in Ubuntu:
Confirmed
Bug description:
Many scanners can no more be used since sane has changed something:
The 3rd-party plug-in the vendor provides as .deb package will still
install. But the scanner is no more recognized.
Scanners that are affected are(besides others):
- Epson Perfection V10
- Epson Perfection V1000
- Epson WorkForce GT-1500
- Brother MFC-8510DN
- Epson Perfection V33
It is to note that the probability that the scanner manufacturers fix
things others broke is below 100%.
