Hello Roland,
Let me echo Michal's welcome.

As you will see from the 'ff-memless-next' driver we are looking to extend
force-feedback support to cover more than just ConstantForce support, and
hopefully bring Linux into scope for force-feedback of AAA game quality.

Mostly this has come from a small group of people reverse engineering the
Logitech wheels, which leads to the 'tailor-made' situation. But we'd like
the systems/interfaces to be device agnostic.

As you how you can help...? As Michal said having a contact at Logitech to
whom we can ask technical questions (off list) would probably be the
greatest help. This would clear up any assumptions we have made, and help
with decisions going forward.

It may also be the case that Logitech is working with studios/game
designers to improve controller performance. If any information can be
feed 'forward' to improve the Linux driver, that would be useful too.

Many thanks,
Simon Wood.
