Hi Sasa Blissful, thank you for posting your concern and I'm sorry to know about your pen issue. Have you installed the tablet driver? And does the tablet driver show "Device connected"? Kindly try the following steps so we will know the root cause of your issue:
Please uninstall the tablet driver and make sure there are no other tablet drivers installed on your computer, whether from Huion or other brands. Having multiple tablet drivers installed on your computer will cause some issues on your tablet's performance such as pen not working.
Install the latest driver for your tablet which you can download from this link, Huion GT-221 Pro Tablet Drivers, and follow the installation process from these articles:
If you still experience the pen issues after performing the steps above, please provide the following information to email@example.com so we can assist you further:

I tried all that and it still doesn't work. Neither the newest driver, nor any others. And all of the advice mentioned as well. It never works. It doesn't show up!
I kinda had the same problem. The pen on my GT 220 V2 didnt work at all no matter what I tried. I figure it must be that the drivers of Huion and WIndows are bugging each other out and causing issues. What i did to fix it and i may have just been lucky, was just completely wipe the huon drivers. Go into your folder and just delete the whole file. Restart and see if that helps. it sucks that the it has to be this way but it was the only way I was able to get my monitor to register my pen again. Still works as of this moment.
