Quick search for the Drag X3 and X2 shows software version v2.0.0.3 from 2021.4.15 is available on the VooPoo website.
I was able to download it to my Mac - I don't do Windows - and don't own any VooPoo mods. LOL

Scroll down and click on Drag series. You will see the X2 and X3. Click on one of those and you will see the link to download the sw.
I would not try updating the X2 or X3 firmware until you get your Window's issues resolved to where your PC recognizes the mod.
So... y'all have tried different "known good" data cables, as Ret1 suggested.
Try your mod on another WinBlows PC. If the mod is recognized on another PC then you have issues with your PC.
Good luck!
