Mouse Emulation
When the touch driver is properly installed, this touch panel works exactly like
a standard mouse for each interface. However, if the system is running under
safe mode, the touch panel calibration may become unsatisfactory due to
disabled drivers. It is recommended to use a standard USB mouse or keyboard
in this mode.
