Help please. Tablet keeps disconnecting and reconnecting + lots of other weird things
My Huion h430p is being really weird. This started a few days ago. It keeps disconnected and reconnected, sometimes it won't show the mouse icon (i've always had this problem but it's normally just when I turn on the computer and goes away after a few minutes but now it's always doing that and it takes longer to fix itself) , it won't click things, and within my art program (FireAlpaca) sometimes it won't draw and it'll disconnect mid stroke. And then it'll let me draw but not erase, delete, or move layers, but everything else it fine. And sometimes it'll say that the eraser tool is selected but it's just not, and it'll draw anyway.
So far I've tried resetting my computer, uninstalling and reinstalling the huion driver, changing the usb I use to plug the tablet into the computer, changing the pen nib, updating FireAlpaca, uninstalling and reinstalling FireAlpaca, just waiting with it unplugged and nothing has changed. If anything it's gotten worse.
It still does this if the side of my hand isn't resting on the tablet and if it's not sitting on the computer.
I've had it for nearly 2 years and it's got a lot of scratches on the surface just from wear and tear but I don't see how that could be the issue. I've never had problems like this and I don't know what to do.
