Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	  Bluetooth HCI USB driver.
	  This driver is required if you want to use Bluetooth devices with
	  USB interface.

	  Say Y here to compile support for Bluetooth USB devices into the
	  kernel or say M to compile it as module (btusb).

config BT_HCIBTUSB_AUTOSUSPEND
	bool "Enable USB autosuspend for Bluetooth USB devices by default"
	depends on BT_HCIBTUSB
	help
	  Say Y here to enable USB autosuspend for Bluetooth USB devices by
	  default.

	  This can be overridden by passing btusb.enable_autosuspend=[y|n]
	  on the kernel commandline.

config BT_HCIBTUSB_POLL_SYNC
	bool "Enable USB poll_sync for Bluetooth USB devices by default"
	depends on BT_HCIBTUSB
	default y
	help
	  poll_sync synchronizes the USB data and event endpoints by
	  prioritizing the later.

	  Say Y here to enable USB poll_sync for Bluetooth USB devices by
	  default.

config BT_HCIBTUSB_BCM
	bool "Broadcom protocol support"
	depends on BT_HCIBTUSB
	select BT_BCM
	default y
	help
	  The Broadcom protocol support enables firmware and patchram
	  download support for Broadcom Bluetooth controllers.

	  Say Y here to compile support for Broadcom protocol.

Annotation

Atlas domain: Driver Families / drivers/bluetooth.
Implementation status: atlas-only.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
