Win32_1394ControllerDevice Class

The Win32_1394ControllerDevice class represents an association between the high-speed serial bus (IEEE 1394 Firewire) Controller and the CIM_LogicalDevice connected to it. This serial bus provides enhanced connectivity for a wide range of devices, including consumer audio/video components, storage peripherals, other computers, and portable devices. IEEE 1394 has been adopted by the consumer electronics industry and provides a Plug and Play-compatible expansion interface.
Namespace value is root/CIMV2.
WMI Provider value is CIMWin32.


Properties

  • AccessState
  • The AccessState property indicates whether the controller is actively commanding or accessing the device (value=1) or not (value=2). Also, the value, "Unknown" (0), can be defined. This information is necessary when a logical device can be commanded by, or accessed through, multiple controllers.

  • Antecedent
  • The Win32_1394Controller antecedent reference represents the 1394 controller associated with this device.

  • Dependent
  • The CIM_LogicalDevice dependent reference represents the CIM_LogicalDevice connected to the 1394 controller.

  • NegotiatedDataWidth
  • When several bus and/or connection data widths are possible, the NegotiatedDataWidth property defines the one in use between the devices. Data width is specified in bits. If data width is not negotiated, or if this information is not available/important to device management, the property should be set to 0.

  • NegotiatedSpeed
  • When several bus and/or connection speeds are possible, the NegotiatedSpeed property defines the one in use between the devices. Speed is specified in bits per second. If connection or bus speeds are not negotiated, or if this information is not available/important to device management, the property should be set to 0.

  • NumberOfHardResets
  • Number of hard resets issued by the controller. A hard reset returns the device to its initialization or 'boot-up' state. All internal device state information and data are lost.

  • NumberOfSoftResets
  • Number of soft resets issued by the controller. A soft reset does not completely clear current device state and/or data. Exact semantics are dependent on the device, and on the protocols and mechanisms used to communicate to it.
