find out USB-port of PID?

I want to set priorities of my usb-devices using rtirq script
I managed to give the ports high priorities but i can't find out wich one is wich.
I need to know wich PID belongs to wich usb port.
top, f.e. only shows me uhci_hcd without the aditional port information:

1256 root     -85   0     0    0    0 S  0.7  0.0   0:02.04   0:02 irq/21-uhci_hcd                             
1251 root     -86   0     0    0    0 S  0.0  0.0   0:00.37   0:00 irq/21-uhci_hcd                                                                  
1260 root     -84   0     0    0    0 S  0.3  0.0   0:00.23   0:00 irq/21-uhci_hcd                             
1263 root     -83   0     0    0    0 S  0.3  0.0   0:00.21   0:00 irq/21-uhci_hcd

how can I find this out?

"man lsof"  or "http://www.noah.org/wiki/Port_to_PID"  will this do......

thanks for trying, Gregor


anybody reading in the future: What I tried to find out is the priority of a specific usb-port. As they are all on one IRQ, wich I can't change, it seams unpossible

Re: find out USB-port of PID?

but you can change the "priority" from the different processes running through it ....(right ?)

Re: find out USB-port of PID?

silly me, it was so easy to find out.....it's an usb-audio-device, simply using it shows up some CPU-usage in htop wich showed me wich priotity it has
