It is. There are a few different methods. If the devices aren't configured to spoof their USB information they typically have manufacturer information in the usb device name, serial, or vendorID. Otherwise searching usb devices by the deviceclass they are using is another good indicator. I've found that these typically show as USB device class 01h (audio) and 08h (mass storage) which is kinda rare. Just have to filter through legitimate USB products.
