+What:	Low Performance USB Block driver ("CONFIG_BLK_DEV_UB")
+When:	3.6
+Why:	This driver provides support for USB storage devices like "USB
+	sticks". As of now, it is deactivated in Debian, Fedora and
+        Ubuntu. All current users can switch over to usb-storage
+        (CONFIG_USB_STORAGE) which only drawback is the additional SCSI
+        stack.
