Attaching USB keyboard freezes trackpad and internal keyboard

Hi everyone,

Spent an hour searching for a solution to this so hopefully it is not a repeat problem. I'm trying to use a wired USB keyboard (DYNEX model no: DX-WKBDSL) with my late 2011 MBP, but whenever I attach it and the Keyboard Setup Assistant pops up my internal trackpad immediately stops responding and my internal keyboard just beeps at me if I hit a key. This prevents me from hitting continue on the setup. If I unplug the USB keyboard, I immediately regain control of my internal input devices. USB hard drives and flash drives cause no problems. I need to be able to use my full usb keyboard so I have a ten key. Can anyone help me?

I've noticed you guys like the EtreCheck thing on here so I just ran it on my machine (obviously without my usb keyboard attached since that would freeze everything). Hope it helps!
