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.
