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*
