+ If you say Y here, you can use driver calls or the sysfs
+ "power/state" file to suspend or resume individual USB
+ peripherals.
+
+ Also, USB "remote wakeup" signaling is supported, whereby some
+ USB devices (like keyboards and network adapters) can wake up
+ their parent hub. That wakeup cascades up the USB tree, and
+ could wake the system from states like suspend-to-RAM.

+ 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.

+config USB_OTG_BLACKLIST_HUB
+ bool "Disable external hubs"
+ depends on USB_OTG
+ 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.
