missing something.... On most FOB's, regardless
of the manufacturer, the RED LED is not wired to
pin 13. While the green LED usually works
correctly because it's tied to pin 12 on the
C-Media chip, the red LED by default is connected
to pin 21.<br clear="none">

There are several reliable sources for non potted
FOB's, but generally they cost more. The SYBA
UAUD71 and the StarTech ICUSBAUDIO are two such
units. They generally cost between $11 and $17
depending on supplier.<br clear="none">
