Troubleshooting Huion driver issues
If you are experiencing issues with your Huion driver, there are several troubleshooting steps you can take to try and resolve the problem.
First, check that your hardware is functioning correctly. Ensure that the USB cable is connected properly and that the USB port on your computer is working. You can do this by touching the pen to the tablet's surface and checking if the pen indicator lights up. If it does not, try connecting to another USB port or replacing the USB cable.

- Press Keys function: Ensure that this is enabled in the driver and that the Press Keys are correctly defined.
- Press lock switch: Check that this is in the unlock position.
- Minimum Pressure: Change the setting from 0% to 1% in the driver.
- TabletMouseSimulation: Set this to "1" in the "misc.ini" file in SAI's program directory.
