I've never know what causes this, but in single user mode some USB 
keyboards on some systems refuse to work. I myself work on an Optiplex 
GX270 that exhibits the same behavior. You can get around it easily 
enough though; at the loader, set hint.atkbd0.disabled=1 and then boot, 
the problem should go away.
