Hi I have the fololwing usb_util -v -t

 Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/12p, 480M
    ID 1d6b:0002 Linux Foundation 2.0 root hub
    |__ Port 1: Dev 2, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M
        ID 04b4:0060 Cypress Semiconductor Corp. Wireless optical mouse
    |__ Port 1: Dev 2, If 1, Class=Human Interface Device, Driver=usbhid, 1.5M
        ID 04b4:0060 Cypress Semiconductor Corp. Wireless optical mouse
    |__ Port 2: Dev 11, If 4, Class=Human Interface Device, Driver=usbhid, 480M
        ID 2454:1292  
    |__ Port 2: Dev 11, If 2, Class=Audio, Driver=snd-usb-audio, 480M
        ID 2454:1292  
    |__ Port 2: Dev 11, If 0, Class=Audio, Driver=snd-usb-audio, 480M

How do I see details for Port 2: Dev 11, If 2, Class=Audio, Driver=snd-usb-audio, 480M

I tried:

./usb_utils -Dsnd-usb-audio  -v
Cannot open snd-usb-audio

also

sudo ./usb_utils -s01:11 -v

nothing

Thank you
