I have multitouch panel controller "Shap TPC". I tried to enable multitouch and adapt driver. I modifed hid-ids.h and hid-multitouch.c. Also I re-build kernel with the multitouch option(http://www.chalk-elec.com/?p=2028) and created IDC file to "/system/usr/idc/" But I can use one touch. also touch point is not correct. see test video. Test video : Full booting log and touch driver are attached. please help me.
