BadUSB keyboard

Hello, i am worried that i just bought a badUSB keyboard. Is there a way to check?
It is a Microsoft Natural Ergonomic 4000 - German version. After i plugged it in, my system was working very hard for long minutes. The keyboard had a scratch out of the box.
Before that, i bought a Czech version of this keyboard, and there Norton didn't even allow the installation - it mentioned a specific virus.
Can i somehow check, if my system got infected by badUSB?
