Why: The code is not actively maintained and platforms are now hard to find.

----------------------------
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.
