Diseqc hauppauge 5500 not working (1 Viewer)

Well. It seems I spoke too soon. It works intermittently.
When checking the log, it succeeds to do a diseqc-command now and then on port AB. AA works fine.

Edit: now it won't work anymore. Weirdest thing. Worked fine on the first channelsearch and then I could tune channels for a while. Now nothing.
