The only annoying thing is that the USB doesn't keep the be-latin1 keyboard setting,
but I'll figure out which file I have to change. (I'm learning now how to use the terminal)
It also happens to me. The keyboard setting resets back to US when i need it to be UK. Normally
all you need to do is to go to /etc/X11/xorg.conf and change the keyboard layout there. However once
KNOPPIX restarts again, the setting defaults back to US.

So the first time I boot it, I have to open a terminal and type: setxkbdmap gb

Everything works fine then...
