The first part of the SANE device name is the backend. As there is no
backend named "acer" this device name doesn't make much sense :-)

Does "scanimage -L" list anything? Maybe you need to edit
snapscan.conf and enter the file name of the firmware file? See man
sane-snapscan for details.

When you run "SANE_DEBUG_SNAPSCAN=255 scanimage -L" you or the
snapscan developers may get a clue what's wrong.
