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:
It should be 3 instead of 1, to match the terminal ID on line 93.
Can someone tell me if this is correct?
