This is from what I read in magazine reviews of the XM301, not from first 
hand experience:
   The XM301 gets its power (5 Volts) from the serial bus.  On the 800XL that
is connected directly to the internal power, on the 1200XL there is a resistor
in series.  Apparently that resistor does not allow enough power to pass to
the XM301.  The mod consists of bypassing the resistor.
