Nexus7 USB configuration after requested USB Accessory and USB Audio

With the help from this website:
http://forum.xda-developers.com/showthread.php?t=1852343

The USB configuration of Nexus 7, after claiming the USB accessory and USB Audio, is shown below. The tools used is lsusb.

I think there is bugs:
(1)  Line 73 to 75, I think it should be:
    73         bInCollection           1
    74         baInterfaceNr( 0)       2
  
The Audio streaming interface has number 2, should I think line 74 should be 2.

2) Line 132, I think it should be:


bTerminalLink           3

It should be 3 instead of 1, to match the terminal ID on line 93.

Can someone tell me if this is correct?
