Here's an xinput test recording. What strikes me as odd is that there are motion events with only an a[0] coordinate, and no a[1] coordinate. This seems related.
As far as I can interpret the wacom-pen2.record, it also seems odd that an x-axis event is not always followed by a y-axis event, like here: # three axes: E: 1300806474.170028 0003 0000 10634 E: 1300806474.170034 0003 0001 7989 E: 1300806474.170035 0003 0018 96 E: 1300806474.170037 0000 0000 0 # three axes: E: 1300806474.178061 0003 0000 10649 E: 1300806474.178069 0003 0001 7988 E: 1300806474.178070 0003 0018 95 E: 1300806474.178072 0000 0000 0 # what is happening here?
