The stylus doesn’t work. There is no driver package that matches the one in the drivers loaded on the machine.
Please post the correct driver package to make the pen work. Or at the least post a link to purchase one that will actually work.
Officially only H2 pen suit to Hi10 air, make sure you are using right stylus.
