Hello all, and thank you so much for your answers! I feel like I need to
clear up a few things here for my own sake, sorry for being slow:

* You are referring to an "I/O" USB card that connects to PCI-E as a
solution, right?
* I don't really know what IRQs are to which port etc, but I have my
soundcard plugged in to one port, and my USB-hub with everything else on on
yet another. I also have USB-ports on the front of my case, which are
connected to the motherboard directly. Can I somehow find out what's
connected to what inside the computer, and how do I modify my IRQ-files to
correspond to where I have my soundcard? Will unplugging/replugging and
using lsusb -t do that for me?

On a different note: If I were to get a new soundcard instead, does anyone
have recommendations of non-USB cards? There seems to be some issues with
PCI-cards and newer motherboards (I have a z77 intel chipset or something)
that uses emulated and not native PCI. I guess this resricts me from using
PCI-cards? (referring to
http://www.linuxmusicians.com/viewtopic.php?f=6&t=10106 ).

I'm using 48khz and 24bit right now, and I record mostly acoustic guitar
and vocals (both singing and rap vocals). Is there any reason for me to run
24bit, maybe I could get away with 16bit? I do not really want to reduce
quality, even by a little, so if there's any reason not to go 16bit I
probably won't.

Again, thank you so much for all responses!

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.
