Thanks, those devices are really surprising. One last question: what's the initial rotation value?

Please checkout the attached rotation card for your device: it should match the description you've given.

For the people interested in the mathematical details, the touch transformations for this device are:
Code:
0 → Mx My
1 → Sxy My
2 → Identity
3 → Sxy Mx
Which means that the center of the mirroring pattern is not sufficient anymore, we also need to know if Mx comes after or before Mx My (modulo 4).
