Well, it looks like the two values really aren't the same.  Two observations.

If there is trailing whitespace in one of the values the puts
statements won't show this.

You're printing the values before you alter one of them.

To get a better debugging perspective try changing

              puts(maquina)
              puts(usuario)
              usuario.chop

to

              usuario.chop
              p(maquina)
              p(usuario)

Which will show the 'inspect' output of the two values right before
you compare them.
