I can run it at 11.6ms (5.8+5.8) full duplex
without any xrun. Lower
latencies work but I get some xrun every now and then.
All USB audio devices move data in one-millisecond packets, so the achievable
latency depends _only_ on the software, not on what device you use.
Anyway I doubt
you can get a greater bandwith with usb 1 at 24bit.
The theoretical limit of USB 1.x is 12 Mb/s (i.e., 1,500,000 bytes/s).
The Audigy 2 NX can do eight channels with 16 bits at 48 kHz (750 KB/s),
but full duplex stereo with 24 bits at 96 kHz would need 1125 KB/s which
is too much considering the protocol overhead.
