Title. I would 100% think that it's a hardware issue BUT it only happens while I'm playing tf2, never while I'm doing something else or playing another game. It stops working completely and if I reconnect it, it takes about 30 seconds to start working again and during this time my game starts freezing/being choppy which sometimes even causes the invis player bug. I also noticed that the game re-execs my class configs a few times while the mouse is connecting. This happens 1-2 times per match so you can see why it's extremely annoying. I tried reinstalling the steelseries engine but it didn't help
