My scanner -- Epson Perfection V550 Photo -- is suddenly not detected

when I enter 'xsane' (via the menu or Alt-F2), it says "no devices

I last used it without any problem 180626.
Since then, I've updated my kernel & some other pkgs.
I've checked the USB physical connection ; the scanner 'ready' light
is on.
I've remerged 'xsane' & 'sane-backends' & rebooted.
Following my notes, I've done :
root:500 ~> sane-find-scanner
...
found USB scanner (vendor=0x04b8 [EPSON], product=0x013b [EPSON
Scanner]) at libusb:001:004
# Your USB scanner was (probably) detected.
# It may or may not be supported by SANE.
# Try scanimage -L and read the backend's manpage.
root:501 ~> scanimage -L
device `epkowa:interpreter:001:004' is a Epson Perfection V550 Photo
flatbed scanner
The first time I ran these commands (I don't remember which),
the scanner itself made the noises it usually does when starting.
This model needs a driver which is not included in 'sane-backends'
& which I downloaded from Nvidia & installed when I got the scanner
2017.
The 'epkowa' driver is installed :
root:505 ~> locate epkowa
/etc/sane.d/epkowa.conf
/usr/lib64/sane/libsane-epkowa.la
/usr/lib64/sane/libsane-epkowa.so.1
/usr/lib64/sane/libsane-epkowa.so.1.0.15
/usr/lib64/sane/archive/libsane-epkowa.la
/usr/lib64/sane/archive/libsane-epkowa.so.1
/usr/lib64/sane/archive/libsane-epkowa.so.1.0.15
My user is a member of the 'scanner' group :
scanner:x:104:purslow
I am puzzled : does anyone have a suggestion what to do next ?
Does the scanner currently show up if you do "lsusb" ?
Does dmesg say anything when you plug the scanner in?
Is it possible that the driver needs updating to deal with a newer
kernel?
