Serial Number String will be derived from Hardware Information Driver (HWINFO). config USB_COMPOSITE_DEVICE bool "Enable composite device driver" depends on USB help Enable composite USB device driver. config USB_MAX_NUM_TRANSFERS int "Set number of USB transfer data buffers" range 1 32 default 4 help Allocates buffers used for parallel transfers.

This prevents deadlock situations where tasks on the system workqueue inadvertently initiate operations that block, such as UART transmission on CDC-ACM, preventing the system work queue from making progress on the USB tasks that would release the task. Without this the system work queue is used for all USB offloaded transfers. config USB_WORKQUEUE_STACK_SIZE int "USB workqueue stack size" depends on USB_WORKQUEUE default 4096 if COVERAGE default 1024 config USB_WORKQUEUE_PRIORITY int "USB workqueue priority" depends on USB_WORKQUEUE default -2 if COOP_ENABLED && !PREEMPT_ENABLED default 0 if !COOP_ENABLED default -1 help By default, USB work queue priority is the lowest cooperative priority. This means that any work handler, once started, won't be preempted by any other thread until finished. source "subsys/usb/class/Kconfig" endif # USB_DEVICE_STACK
