If people have questions about and/or problems with the REB 1100 I think these links will be very useful indeed.

This gets you the USB driver, the eBookLibrarian installer, the users guide and a firmware upgrade [version 2.0.305], all for the 1100.

This site gives lots of useful info for the 1100, 1200 and GEB 1150, it's actually called REB 1200 for dummies.
You can download pretty much all that's available, Rocket Librarian that converts HTML and TXT files to RB format [with Mobipocket Creator and Amber ABC Lit Converter you can make most any file into an HTML or TXT file], and much more, there's even even linux utilities for the REB 1100!
Enjoy!
