MEDION MD 90091 Scanner not detected under Ubuntu 20.04
Hi ! Despite all good advices I can't get my new (old) USB scanner detected & working on Ubuntu 20.04 : Medion/Lifetec/Tevion/Cytron MD 90091 is not supposed to be compatible as it's NOT listed in 20-sane.hwdb file
sudo sane-find-scanner -q
gives
could not fetch string descriptor: Pipe error
could not fetch string descriptor: Pipe error
found USB scanner (vendor=0x05da [Prolific Technology Inc.], product=0x3022 [USB Scanner ]) at libusb:002:003
I have enriched config files for Microtek & Microtek2 with
# Prolific Technology Inc. | MEDION MD90091 | USB Scanner
ATTRS{idVendor}=="05da", ATTRS{idProduct}=="3022", ENV{libsane_matched}="yes"
but doesn't work, even after reboot
I couldn't find any firmware upgrade.
thank you in advance for your help ! Xmas time ;-) Regards, Olivier
