----------------------------



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.
