Actually with _every_ digital audio you get latency. "Zero Latency" is only
possible in analog audio processing and even there it might fail do to phase-
shifts of capacities and coils.
In the digital world there is always some delay in the analog-digital-
converter and in the digital-analog-converter. There is always some buffering
between the converters and the chip of the sound-device. And then there is the
transport to the pc's ram and cpu (with buffering). So even with PCI-cards you
always have latency. But with usb (and firewire) you have a transport
additional to the pci-bus, which adds extra latency.
And it doesn't matter which usb-device you use, if it uses usb as transport,
they all have the same latency in your machine.
Have fun,

Btw.: all USB soundcards have the same latency.
I guess that's because USB has a certain required latency? Interesting,
either way...
