Thanks.

you are right. That's not necessary.
We already processed.

The final purpose of my approach is that the correct working of the AFO
multi-Touch module in All distribution of Linux.
Therefore, the inclusion of the VID,PID(AFO Touch Module) to the
hid-multitouch module is basically needed also for old version of the Linux
distribution.

Is this really necessary? Why doesn't HID_DG_CONTACTID matching work for the
to automatically trigger HID_GROUP_MULTITOUCH-based binding?
