I don't know if that scanner (or the plustek backend in general) works
with MacOS X (maybe other developers/users can talk abou that). But
maybe some more debugging helps to find out what's wrong:

Looks fine. Well, the negative bus number of libusb looks odd, I
thought that was fixed in newere libusb versions. But it shouldn't harm.

Ok, so sanei_usb also found the scanner.

The Plustek backend gets loaded correctly.


SANE_DEBUG_PLUSTEK=255 scanimage -L

for what the plustek backend actually does.
