v1..v2: remove "can't use SCSI commands" and "does not use libusual". I meant

+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.
