USB 2.0 has a built-in hardware latency. If you are unwilling to go through the trouble of special coding, be sure to use the USB Dongles alone on their own PCI USB Card, this will minimize latency.
As Leif said earlier USB latency/jitter is not a problem. Dongles sample into internal buffer. You get this buffer over USB, you are fine as long as it doesnt overflow.
Sync dongle clocks (feed them from one clock source) and there will be no jitter over time.
