I understand. I have been spending alot of time in it my self. I will look
deeper into the socket, and which of them that have been closed and at which
time... But I think I have checked this a million times.. But I will try
again! :-)

Yes I can try to swap the devices. You mention that the master device should
be carefully choosen. I what way?
I have just assumed that my server should be the master, and thats that.
What should I taken in to consideration?

-Once again thanks for all the quick answers! :-)
