Alas, after the first successful scan, even iscan doesn't work anymore
I am really confused ...

It works!
Well, the response of scanimage -L is somehow erratic -most of the
time it
Maybe I should point out here that the same scanner (with the same USB
cable!) works well on my laptop: Ubuntu 10.10, with
xsane: 0.997-2ubuntu3
libsane: 1.0.21-2ubuntu2
Problems arise only with my desktop: Ubuntu 11.10, with
xsane: 0.998-3ubuntu1
libsane: 1.0.22-2ubuntu2

FWIW, you may want to try the epkowa backend included with Image Scan!
for Linux available here:

Now it is guess work why the device is temporarily unavailable when
trying to reset it, but replies just fine to the status query to comes
immediately after.
Timing issue? Perhaps the two bytes
Would this explain why the backend works the first time it is called
from within a shell, and then stops working until a new shell is
opened (as I described earlier)?
No... unless the first (successful) operation leaves some data behind
(environment variable?) that causes the second (failed)
