On the device settings, as I've installed all specific drivers, they vibration function appears and works correctly when tested with the left analog stick, but when I enable it in games (from emulators to specific Windows builds) it just doesn't work.
That's gonna be an emulator code thing. You need to check the emulator's options and/or check their support forum for what ever emulator you are using...
I honestly don't know then other to say perhaps you need a specific driver for that functionality other than the Windows built-in driver.
You say "joypads." Is there more than one that does this? What's the make and model of the joypad/s?
Yes, it's more than one. The first is a USB joypad, the second one is a PS2 joypad with USB adapter
