I tried enabling the following config options to turn on USB tracing, but
didn't get any tracing output when I rebooted:

CONFIG_DEBUG_FEATURES=y
> CONFIG_USBDEV_TRACE=y
> CONFIG_USBDEV_TRACE_NRECORDS=5000
> CONFIG_USBDEV_TRACE_STRINGS=y
> CONFIG_NSH_USBDEV_TRACE=n
> CONFIG_NSH_ARCHINIT=y
> CONFIG_USBMONITOR=y
> CONFIG_USBMONITOR_STACKSIZE=2048
> CONFIG_USBMONITOR_PRIORITY=50
> CONFIG_USBMONITOR_INTERVAL=1
> CONFIG_USBMONITOR_TRACEINIT=y
> CONFIG_USBMONITOR_TRACECLASS=y
> CONFIG_USBMONITOR_TRACETRANSFERS=y
> CONFIG_USBMONITOR_TRACECONTROLLER=y
> CONFIG_USBMONITOR_TRACEINTERRUPTS=y
>

I got these from this page:
