Why not just get a PCI USB card, far cheaper and there are plenty here will attest to them, me being one, inteck 4 port PCI usb card, solved all my USB CV1 issues and still going strong 2 years later. 😉
this is one looks like it will do the job. Just noticed it has asmedia usb controller which is also what my current board failed with. So i’m not sure how well this will do. the usb 3.1 gen 2 might be a different story with that controller?
