[sane-devel] Sane no longer works

[Steve Cohen]

I have a Canon LIDE 220 scanner. I am running
Ubuntu 20.04.3 LTS, 64-bit

  xsane -v
Gtk-Message: 14:37:04.462: Failed to load module "canberra-gtk-module"
xsane-0.999 (c) 1998-2013 Oliver Rauch
   E-mail: Oliver.Rauch at xsane.org
   package xsane-0.999
   compiled with GTK-2.24.32
   with color management function
   with GIMP support, compiled with GIMP-2.10.18
   XSane output formats: jpeg, pdf(compr.), png, pnm, ps(compr.), tiff, txt

This setup used to work well.  I don't use it often but it no longer 
does. On "scanning for devices" I get "Failed to open device 
genesys:libusb:003:029 - Invalid Argument.

$ scanimage --test
Output format is not set, using pnm as a default.
scanimage: open of device genesys:libusb:003:031 failed: Invalid argument

Can someone point me to a solution for this?

Thanks.
