If you've got the same light on at both ends then that means that you've got
outputs at both ends, trying to drive that wire...

Did this setup work with the cable you're using now? If not, the cable wiring
may be part of your problem, a lot of times signals are crossed over.

This suggests that the port is working, but no other lights suggest that the
wires aren't coming through for the other signals. They may instead be
looped back at the connector end of the cable.

Is this one of those cables where you can open up the ends by removing the
connector shells? Might be worth a look...

Not if you've got two outputs tied together, that's not gonna work. :-)

A bit of wire can help that.
