SBP-2

The SBP2 family (Serial Bus Protocol 2) provides support for, and access to, devices attached to the FireWire bus that use the SBP-2 transport protocol. The SBP2 family is a client of the FireWire family. SBP-2 devices require FireWire to run.

Bundle identifier:

com.apple.iokit.IOFireWireSBP2

Device interface:

The SBP2 family provides a device interface that exports an interface for sending SBP-2 ORBs to a device.

**Table A-9** Clients and providers of the SBP2 family
	Client of the nub	Provider for the nub
Action	Drives a device that uses the SBP-2 transport protocol.	Provides SBP-2 transport services
Example	A driver for a typical FireWire hard disk drive is a client of the SBP2 family but is a member of the mass storage family.
Classes	A client driver communicates with the SBP2 family through an instance of IOFireWireSBP2LUN. An instance of this class is created for each LUN (Logical Unit Number) found in a configuration ROM unit directory; this instance matches your driver and loads it into the kernel.	SBP2 family-member drivers should inherit from the IOFireWireSBP2Target class.
Notes	The most common client family is the Storage family.
