I forgot that you use inputenc to convert from UTF-8. In such a case ß
is not a character but a sequence of two characters the first of which
is active.

Apparently something strange is done inside babel, with babel in xetex
I get the same result as you. I tried the following file using
polyglossia:

\documentclass{article}
\usepackage{polyglossia}
\setdefaultlanguage{german}
\usepackage{xltxtra}
\begin{document}
\showhyphens{geißeln}
\showhyphens{wußte}
\showthe\lefthyphenmin
\showthe\righthyphenmin
\end{document}


The result is:

*********************** \showhyphens: ***********************

Underfull \hbox (badness 10000) detected at line 6
 \EU1/lmr/m/n/10 geißeln

*************************************************************


*********************** \showhyphens: ***********************

Underfull \hbox (badness 10000) detected at line 7
 \EU1/lmr/m/n/10 wuß-te

*************************************************************

At least it can hyphenate wußte but I cannot understand why geißeln is
not hyphenated. Both babel and polyglossia set \lefthyphenmin and
\righthyphenmin to 2, thus hyphenation is allowed.
