CONFIG_EXAMPLES_USBSTRG_DEVMINOR3 and CONFIG_EXAMPLES_USBSTRG_DEVPATH3
Similar parameters that would have to be provided if CONFIG_EXAMPLES_USBSTRG_NLUNS
is 3.
If CONFIG_USBDEV_TRACE is enabled (or CONFIG_DEBUG and CONFIG_DEBUG_USB), then
the example code will also manage the USB trace output. The amount of trace output
can be controlled using:
CONFIG_EXAMPLES_USBSTRG_TRACEINIT
Show initialization events
CONFIG_EXAMPLES_USBSTRG_TRACECLASS
Show class driver events
CONFIG_EXAMPLES_USBSTRG_TRACETRANSFERS
Show data transfer events
CONFIG_EXAMPLES_USBSTRG_TRACECONTROLLER
Show controller events
CONFIG_EXAMPLES_USBSTRG_TRACEINTERRUPTS
Show interrupt-related events.
Error results are always shown in the trace output
