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.

config USB_ACM
	tristate "USB Modem (CDC ACM) support"
	depends on TTY
	help
	  This driver supports USB modems and ISDN adapters which support the
	  Communication Device Class Abstract Control Model interface.
	  Please read <file:Documentation/usb/acm.rst> for details.

	  If your modem only reports "Cls=ff(vend.)" in the descriptors in
	  /sys/kernel/debug/usb/devices, then your modem will not work with this
	  driver.

	  To compile this driver as a module, choose M here: the
	  module will be called cdc-acm.

config USB_PRINTER
	tristate "USB Printer support"
	help
	  Say Y here if you want to connect a USB printer to your computer's
	  USB port.

	  To compile this driver as a module, choose M here: the
	  module will be called usblp.

config USB_WDM
	tristate "USB Wireless Device Management support"
	help
	  This driver supports the WMC Device Management functionality
	  of cell phones compliant to the CDC WMC specification. You can use
	  AT commands over this device.

	  To compile this driver as a module, choose M here: the
	  module will be called cdc-wdm.

config USB_TMC
	tristate "USB Test and Measurement Class support"
	help
	  Say Y here if you want to connect a USB device that follows
	  the USB.org specification for USB Test and Measurement devices
	  to your computer's USB port.

	  To compile this driver as a module, choose M here: the
	  module will be called usbtmc.

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.
