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.

Thank you,

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.

That's fair since they don't need to track the fingers.

Well, it is not a pure HID issue.  It is more of how we want to
support MT on Linux issue.

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?

What else do you need me to clarify? I am all ears and I am ready to
clarify any thing that puzzles you.
