+config USB_ANNOUNCE_NEW_DEVICES
+       bool "USB announce new devices"
+       help
+         Say Y here if you want the USB core to always announce the
+         idVendor, idProduct, Manufacturer, Product, and SerialNumber
+         strings for every new USB device to the syslog.  This option is
+         usually used by distro vendors to help with debugging and to
+         let users know what specific device was added to the machine
+         in what location.
+
+         If you do not want this kind of information sent to the system
+         log, or have any doubts about this, say N here.

+config USB_DEFAULT_PERSIST
+       bool "Enable USB persist by default"
+       default y
+       help
+         Say N here if you don't want USB power session persistence
+         enabled by default.  If you say N it will make suspended USB
+         devices that lose power get reenumerated as if they had been
+         unplugged, causing any mounted filesystems to be lost.  The
+         persist feature can still be enabled for individual devices
+         through the power/persist sysfs node. See
+         Documentation/usb/persist.txt for more info.
+
+         If you have any questions about this, say Y here, only say N
+         if you know exactly what you are doing.
+
+config USB_DYNAMIC_MINORS
+       bool "Dynamic USB minor allocation"
+       help
+         If you say Y here, the USB subsystem will use dynamic minor
+         allocation for any device that uses the USB major number.
+         This means that you can have more than 16 of a single type
+         of device (like USB printers).
+
+         If you are unsure about this, say N here.
+
+config USB_OTG
+       bool "OTG support"
+       depends on PM
+       default n
+       help
+         The most notable feature of USB OTG is support for a
+         "Dual-Role" device, which can act as either a device
+         or a host. The initial role is decided by the type of
+         plug inserted and can be changed later when two dual
+         role devices talk to each other.
+
+         Select this only if your board has Mini-AB/Micro-AB
+         connector.
+
+config USB_OTG_WHITELIST
+       bool "Rely on OTG and EH Targeted Peripherals List"
+       depends on USB
+       help
+         If you say Y here, the "otg_whitelist.h" file will be used as a
+         product whitelist, so USB peripherals not listed there will be
+         rejected during enumeration.  This behavior is required by the
+         USB OTG and EH specification for all devices not on your product's
+         "Targeted Peripherals List".  "Embedded Hosts" are likewise
+         allowed to support only a limited number of peripherals.
+
+config USB_OTG_BLACKLIST_HUB
+       bool "Disable external hubs"
+       depends on USB_OTG || EXPERT
+       help
+         If you say Y here, then Linux will refuse to enumerate
+         external hubs.  OTG hosts are allowed to reduce hardware
+         and software costs by not supporting external hubs.  So
+         are "Embedded Hosts" that don't offer OTG support.
+
+config USB_OTG_FSM
+       tristate "USB 2.0 OTG FSM implementation"
+       depends on USB
+       select USB_OTG
+       select USB_PHY
+       help
+         Implements OTG Finite State Machine as specified in On-The-Go
+         and Embedded Host Supplement to the USB Revision 2.0 Specification.
