Method 2. Use another USB cable to test.
If the above two methods won't work, please check if the USB cable is damaged. Please use another USB cable to test and see if it will work or not.
Method 3. Use another computer to test.
If you have installed the driver properly without any issue but the problem still persists, please use another computer to test. If it works on another computer, it is possible that the previous computer system lacks some components which caused the driver to fail to connect.
If you have tried all the methods mentioned above but it still shows Device disconnected and the pen won't move after uninstalling the driver, then it might be possible that the port of the graphic tablet is damaged or the graphic tablet itself is damaged.
