USB2 bandwith (theoretical) is 480 Mbit/s
1 channel @ 96khz / 24bit means 96000 * 24 = 2.19 Mbits per second.
480 / 3 (yep, I round it to the superior value) means... 160 damn theoretical channels at 96khz with usb2.
Even if we take the half, which is a pretty real value, we have 80 channels.
So do you really think somebody out there has the need for more in an external interface?
