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_STORAGE
	tristate "USB Mass Storage support"
	depends on SCSI
	help
	  Say Y here if you want to connect USB mass storage devices to your
	  computer's USB port. This is the driver you need for USB
	  floppy drives, USB hard disks, USB tape drives, USB CD-ROMs,
	  USB flash devices, and memory sticks, along with
	  similar devices. This driver may also be used for some cameras
	  and card readers.

	  This option depends on 'SCSI' support being enabled, but you
	  probably also need 'SCSI device support: SCSI disk support'
	  (BLK_DEV_SD) for most USB storage devices.

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

if USB_STORAGE

config USB_STORAGE_DEBUG
	bool "USB Mass Storage verbose debug"
	help
	  Say Y here in order to have the USB Mass Storage code generate
	  verbose debugging messages.

config USB_STORAGE_REALTEK
	tristate "Realtek Card Reader support"
	help
	  Say Y here to include additional code to support the power-saving function
	  for Realtek RTS51xx USB card readers.

	  If this driver is compiled as a module, it will be named ums-realtek.

config REALTEK_AUTOPM
	bool "Realtek Card Reader autosuspend support"
	depends on USB_STORAGE_REALTEK && PM
	default y

config USB_STORAGE_DATAFAB
	tristate "Datafab Compact Flash Reader support"
	help
	  Support for certain Datafab CompactFlash readers.
	  Datafab has a web page at <http://www.datafab.com/>.

	  If this driver is compiled as a module, it will be named ums-datafab.

config USB_STORAGE_FREECOM
	tristate "Freecom USB/ATAPI Bridge support"
	help
	  Support for the Freecom USB to IDE/ATAPI adaptor.
	  Freecom has a web page at <https://www.freecom.de/>.

	  If this driver is compiled as a module, it will be named ums-freecom.

config USB_STORAGE_ISD200
	tristate "ISD-200 USB/ATA Bridge support"
	help
	  Say Y here if you want to use USB Mass Store devices based
	  on the In-Systems Design ISD-200 USB/ATA bridge.

	  Some of the products that use this chip are:
