Comment 1 for bug 570135

Hello, I have done some checks on this problem using a N52te:
- I configured D-PAD with mouse axis: X takes motion into account without pystromo
- when using pystromo to send REL_event, whatever the button `xev` detects the REL event but mouse coordinates aren't updated so X consider it had to move the pointer at the same position. It seems the event.value content isn't taken into account
