Hi Luca,
In your diff.sane.txt I've found these two entries (problem seems
related to settings of c189:130) :
< openat(AT_FDCWD, "/run/udev/data/c189:130", O_RDONLY|O_CLOEXEC) = 33
< fstat(33, {st_mode=S_IFREG|0644, st_size=670, ...}) = 0
< fstat(33, {st_mode=S_IFREG|0644, st_size=670, ...}) = 0
< read(33, "I:4009030\nE:ID_VENDOR=Brother\nE:"..., 4096) = 670
< read(33, "", 4096) = 0
< close(33) = 0
< getrandom("\213%[2\301\372\rH\260\347\r\2\374\2340\344", 16, GRND_NONBLOCK) =
16

> openat(AT_FDCWD, "/run/udev/data/c189:130", O_RDONLY|O_CLOEXEC) = 411
> fstat(411, {st_mode=S_IFREG|0644, st_size=670, ...}) = 0
> fstat(411, {st_mode=S_IFREG|0644, st_size=670, ...}) = 0
> read(411, "I:4009030\nE:ID_VENDOR=Brother\nE:"..., 4096) = 670
> read(411, "", 4096) = 0
> close(411) = 0
> getrandom("\"\215\241\234r\351\310\233\25\f\\\374`\3304N", 16, GRND_NONBLOCK)
> = 16
So next step would be:
1. 'sane-find-scanner'
last time you did this output was
'found USB scanner (vendor=0x04f9 [Brother], product=0x035d [MFC-1910W])
at libusb:002:006'
But please run it again for being sure, usb port could have changed...
2. 'udevadm info -a /dev/bus/usb/002/006' (/002/006 has to be replaced
by output of 1.)
Post result here (Complete device please. Looks like: looking at device
'/devices/pci0000:00/0000:00:14.0/usb3/3-3', parent devices are of no
interest)
3. 'udevadm test /devices/pci0000:00/0000:00:14.0/usb3/3-3'
(/devices/pci0000:00/0000:00:14.0/usb3/3-3 has to be replaced by output
of 2.)
Post result here (Complete please. For interest are lines like : handling
device node '/dev/bus/usb/003/004', devnum=c189:259, mode=0664, uid=0, gid=0
preserve permissions /dev/bus/usb/003/004, 020664, uid=0, gid=0
preserve already existing symlink '/dev/char/189:259' to '../bus/usb/003/004')
Thanks

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%.
