One developer who has worked with audio streaming on USB and FireWire
reported that USB needed much more CPU attention compared to FireWIre.
Can anyone comment on the truthfulness or falsehood of that statement?
We anticipate that we may be sending both isochronous and
asynchronous data in both directions on the bus, streaming multiple,
high frequency audio channels, while at the same time, running CPU
intensive software on the host. Would we be better off with FireWire
compared to USB? Would it make a big difference?
Thank you for your insight!
