+config USB_DEBUG
+ bool "USB verbose debug messages"
+ depends on USB
+ help
+ Say Y here if you want the USB core & hub drivers to produce a bunch
+ of debug messages to the system log. Select this if you are having a
+ problem with USB support and want to see more of what is going on.

+config USB_DEVICEFS
+ bool "USB device filesystem"
+ depends on USB
+ ---help---
+ If you say Y here (and to "/proc file system support" in the "File
+ systems" section, above), you will get a file /proc/bus/usb/devices
+ which lists the devices currently connected to your USB bus or
+ busses, and for every connected device a file named
+ "/proc/bus/usb/xxx/yyy", where xxx is the bus number and yyy the
+ device number; the latter files can be used by user space programs
+ to talk directly to the device. These files are "virtual", meaning
+ they are generated on the fly and not stored on the hard drive.
+
+ You may need to mount the usbfs file system to see the files, use
+ mount -t usbfs none /proc/bus/usb
+
+ For the format of the various /proc/bus/usb/ files, please read
+ <file:Documentation/usb/proc_usb_info.txt>.
+
+ Please note that this code is completely unrelated to devfs, the
+ "/dev file system support".
+
+ Most users want to say Y here.
+
+config USB_BANDWIDTH
+ bool "Enforce USB bandwidth allocation (EXPERIMENTAL)"
+ depends on USB && EXPERIMENTAL
+ help
+ If you say Y here, the USB subsystem enforces USB bandwidth
+ allocation and will prevent some device opens from succeeding
+ if they would cause USB bandwidth usage to go above 90% of
+ the bus bandwidth.
+
+ If you say N here, these conditions will cause warning messages
+ about USB bandwidth usage to be logged and some devices or
+ drivers may not work correctly.
+
+config USB_DYNAMIC_MINORS
+ bool "Dynamic USB minor allocation (EXPERIMENTAL)"
+ depends on USB && EXPERIMENTAL
+ 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_SUSPEND
+ bool "USB suspend/resume (EXPERIMENTAL)"
+ depends on USB && PM && EXPERIMENTAL
+ help
+ If you say Y here, you can use driver calls or the sysfs
+ "power/state" file to suspend or resume individual USB
+ peripherals. There are many related features, such as
+ remote wakeup and driver-specific suspend processing, that
+ may not yet work as expected.
+
+ If you are unsure about this, say N here.
+
+
+config USB_OTG
+ bool
+ depends on USB && EXPERIMENTAL
+ select USB_SUSPEND
+ default n
+
+
+config USB_OTG_WHITELIST
+ bool "Rely on OTG Targeted Peripherals List"
+ depends on USB_OTG
+ default y
+ 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 specification for all devices not on your product's
+ "Targeted Peripherals List".
+
+ Otherwise, peripherals not listed there will only generate a
+ warning and enumeration will continue. That's more like what
+ normal Linux-USB hosts do (other than the warning), and is
+ convenient for many stages of product development.
