Oh well, that's old :-) Anyway, it should work.

Something is wrong here, the mustek_usb backend doesn't support
halftone mode at all. And as far as I remember, the original Mustek
backend didn't either. Do you mean lineart (black/white) mode?

I just tried lineart mode with this scanner and the result was ok as
far as I could see. Could you show us the exact options you use for
scanimage and put an example image somewhere on a website?

For the original Mustek version, ask Mustek for help.
