All that on two ports? On the same irq?

He has only two USB ports for audio/midi, kb, rodent... and two more things.
Depending on price/needs, my first option would be to get an internal

card, PCI or PCIe. If you are using a USB1.1 device at 16bit/48k anyway, I

would suggest the original ensoniq es1370 cards (should be able to find

free) as they are reasonably quiet, have midi and just work with just

about anything. For 24bit, look for the ice1712 based cards. You will

probably have to pay more for them though. If you want to make use of the

USB device you have, get a PCI(e) USB port. It should have it's own irq if

it goes in the right slot. After an es1370 this is probably the cheapest

solution... you may even find one of these for free too from back when USB

was just coming out.
