[Technical] League doesn't seem to play well with mouse/keyboard in USB hubs that disconnect

Pretty self-explanatory. I've now got that usb hub running with just the mouse and keyboard so it won't have issues (wtf is the point of it having a separate power source though if it can't take more than 2 slots?!?!), but when I earlier had 3 things plugged into it it had issues. I was able to actually get my kb and mouse both working, but the first two times it took longer to start working in-game than elsewhere in my client (which quickly recovered kb/m functionality otherwise). If it helps, I was using a razor blackwidow and a logtich g5000 or something like that I think and the mouse came back before the keyboard when I unplugged everything after dcing, but otherwise they both came back in-game about the same time.
