usb2.0 is build into windows 7, there shouldn't be any special drivers for it. windows 7 does not natively support usb3.0, you need drivers for that.
Herein lies the next problem, I'm trying to install the 3.0 drivers and it's claiming my computer doesn't meet the minimum requirements to install, frustrating
Edit: It's not quite the end of the world is it? I'm pretty sure that's what was causing drop outs and audio problems for my PC, just done another latency test and there's no problems. Do I even need it?
Edit2: Nvm, just let it run longer and now it's the USB 1.1 and 2.0 ports that's causing me latency :/
Edit3: It seems to be whenever I plug something into a USB 3.0 slot, the latency goes up - is this because my devices (mouse, keyboard, headset and wireless adapter) aren't USB 3.0? I only have three 2.0 slots, and it's not really possible for me to use an ethernet cable
