USB 3 would gain me nothing,

However, the issue can't be solved by making the used USB port head of
the USB ports. This might help a little bit, but the major issue is,
that you only can assign real-time priority to all USB ports.

I can't comment a PCI or PCIe card to USB, but at least it would share
real-time priority with all the other USB ports and it might cause
additional issue by sharing a quasi split PCIe slot. Again, I can't
comment such USB cards, but I know that several PCIe slots often are
not several slots, they are quasi one split slot.
