so on which pci device is my sound card (Native Instruments RigKontrol2) attached
if this is the output of lsusb?

Hello, I'm trying to find out if plugging my
USB soundcard in
different USB ports of my laptop makes any difference. If I got it
right, I should choose the one with the lowest IRQ. So, with "lspci
-v" I can see I have 4 "USB Controller" devices, each with their
own IRQ (lowest one is 16 which seems to be shared by video
card...) - but how do I know which one my sound card is plugged
into?
To see which bus belongs to which PCI device, run:
ls -l /sys/bus/usb/devices/usb*
