See, you already need some out-of-tree driver to make this adapter work
with standard Linux - and you expect the driver that comes with Xenomai
to work with it out of the box?

The question is now *what* is special about this adapter and its driver.
Where do you have the code from? What's its license?

IRQs only show up there when they are in use, and that is the case when
the port is opened (ie. the test program is running).
