My experience with the Momo pedals is the following: I tried really a lot of all those fixes proposed all over the internet... in terms of software, hardware, configuration, whatever. Some of them changed nothing, others worked temporarily, however, problems came back after a few month and even worse then (decalibration, spikes, etc.). These pedals simply suffer from intensive usage.
The only fix that really helped finally was to throw them on the rubbish dump and to replace them by a plug-compatible pedal set from ECCI. Very expensive though, but I didn't see another way...
