That's the known problem with libusb (or the MacOS X USB system?).

Can you enable debugging for fujitsu also? It's easier to understand
if the fujitsu messages are also enabled.

This seems to be the first error.

My guess is: the fujitsu backend uses fork () and this doesn't work
correctly on MacOS X. So if you want support for your scanner, the
fujitsu backend must be converted to use the sanei_thread API instead
of fork().

Have a look at the archive of sane-devel for a discussion about the
fork problems.
