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.
