You can do USB with the 1150, using a program called GEB Librarian. Ebookwise was promoting it when they first released the 1150, but I don't think they link to it any more. Development seems to have stopped back in 2005, but it does work (for me anyway). It also converts to 1150 format from text, html, doc, and opf (conveniently what you get when you break open a .lit file). I really can't imagine using the 1150 without it.
