The part of the usbmon trace that you attached doesn't show any audio input at all -- no errors, nothing. Here's a hint: Look through the usbmon file for lines containing " E " -- those are the errors. Extract a portion starting back from there about 100 lines, and include some of the " E " lines so we can see them. Another hint: The important lines are the ones containing "Zi:1:002:2" -- the actual string may be slightly different, but it will definitely contain "Zi" and it will match the " E " lines.
