They also report 2nd touch X/Y values shifted down 1 byte (where pressure was). This results in jumpy 1 finger touch and totally invalid 2nd finger data. For touch detection, switch to a Touch Present single bit that all versions of Bamboo support. For touch 2 offset, calculate offset based on a bit that is set different between the two packet layouts. Since touch pressure reports were removed from driver, there was no need to be reading pressure any more.
