Good point. But they don't typically share those IRQs, do they? Or if
they do, isn't it with a PCI slot, so that you might benefit by moving
anything in that slot?

I've certainly had some audible noise generated by video activity, but
not a lot and it's rare. But I wouldn't want it if I was trying to
record the cleanest signal possible.

Just to make sure I understand what you're saying here: 24/96 means
2.3Mbps, so full duplex would mean 4.6Mbps, which is less than the
USB1.1 12Mbps hard limit. But there's so much overhead in USB traffic
that you don't really ever come close to having 12Mbps available in
USB1.1, and in fact wouldn't have 4.6MBps available for one channel
24/96 full duplex? Do I have you right?

Thanks again!
