I didn't follow this thread, perhaps nobody linked against
https://support.focusrite.com/hc/en-gb/articles/208095469-USB-2-0-vs-USB-3-0
or similar until now. I experience much more issues with my
professional PCIe card, than with my prosumer USB device ;). OTOH USB
could be tricky. You might need to unbind USB ports and/or to test all
available USB ports (unbinding sometimes is impossible), an USB slot
bracket might be required to do this.
