I tested a small USB keyboard and the RF wireless Prolink PCBO 5304G http://www.prolink2u.com/new/products/index.php?cid=193 it works fine on the eDGe. I was really surprised to see the RF wireless dongle for the keyboard/mouse set working. Nice! Even the mouse "works", you can move the text cursor with it, still a separate mouse cursor would be better.
