This page describes how I’ve solved the problem of adding an interactive terminal to my Linksys NSLU2 (aka Slug) with a USB keyboard and an LCD display. My soltuon consists of some C++ code (about 1000 lines) and some hardware to attach the display to USB. I hope that it will be useful to other Slug users.
