  • Hi Mitsuha Miyamizu, have you installed the driver? If you have, which version is it? Please try to uninstall and reinstall the driver and see if it will resolve the issue. If you are using Windows, please make sure that your tablet is not connected to your computer, your antivirus is turned off and all your programs are closed while installing the driver.


    Try connecting your tablet and/or your keyboard to a different USB port. If you are using a USB hub or adapter, please try using a different one. If you have access to another computer, please try to check if the issue persists when using a different computer.


    Best Regards,
