So close to perfection - USB performance?

Okay, so I've got High Sierra running on my i3-4130T, H97I-Plus system. I tinkered around with audio but didn't have much luck, so rather than continue to beat my head against the wall I just ordered a USB sound card that's natively supported.

USB file transfers from this setup seem really, really slow, and the USB3 ports aren't working at all. Is there a kext I need to install, or something? For whatever reason my Google-fu isn't finding anything specifically related to USB on the H97 chipset.
