Hi Mohamed, I am glad that you've initiated this email thread. Otherwise, I would have to find a proper way to explain the current status of Wacom MT support. Please see my comments inline.

As most of you know, the current Wacom two finger touch devices have been supported on Linux since last Oct. However, they are not supported with the current in-kernel MT protocol, aka, MT type A protocol. I know you would ask me why. The reason is simple: it doesn't support the Wacom case - finger tracking. If you wonder why I don't work with the other developers to support Wacom MT case, I can assure you that I am working with them. We will support Wacom MT devices once the appropriate protocol is available. > N-Trig based devices and Stantum ones are the most compliant, That's fair since they don't need to track the fingers. > so Wacom situation needs to be clarified specially considering they are HID > devices (meaning similar to the others devices which respect the > protocol). Well, it is not a pure HID issue. It is more of how we want to support MT on Linux issue. > This impact very much the decision of a Linux user wanting to buy wacom mt device. I think end users have already got the Linux support from Wacom. Can you share the specific issues that are preventing Linux end users from buying a Wacom MT devices? If I didn't misunderstand your point here, you are talking about Linux users, not Linux developers/hackers, right? > Ping can you clarifie the situation of wacom based devices ? What else do you need me to clarify? I am all ears and I am ready to clarify any thing that puzzles you.
