Just for further clarification,
I tried downloading the sane backends from debian experimental (1.0.27)
with no luck.
After download and building from the git repository, and setting
SANE_USB_WORKAROUND=0 it works (SANE_USB_WORKAROUND=1 does not work).
Thanks for the nudge in the right direction - I think I'm all set to go now.
