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.
