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?


The problem is lspci reports busses in the form "00:1d.0" while lsusb

in the form "Bus 001 Device 002" - and plugging my soundcard in another

port changes only the Device of lsusb, not the Bus... so I'm pretty

much lost.


any help appreciated,

renato
