1. Please make sure your Star USB cable has connected to computer? If not, please connect it.
2. When the stylus is far away from the sensitive height of the tablet, please check the LED light of the tablet is on or off. If it always blinks, please unplug and plug again or try to connect it to another USB port.
3. Try to remove the driver and reboot the computer. When the system returns to the desktop, please connect the tablet to the computer directly (doesn’t need install driver) and test whether you can use the stylus to control the cursor or not.
4. If the stylus also can’t control the cursor even you have not installed the driver, please try to test the Star with another computer.
When you test with another computer and the problem still exists, there should be hardware problems with the tablet or stylus.
