1394 Controller Device

The Win32_1394ControllerDevice class has these properties.

AccessState
Data type: uint16
Access type: Read-only

Indicates whether the controller is actively commanding or accessing the device. This information is necessary when a logical device can be commanded by, or accessed through, multiple controllers.

Unknown (0)

Active (1)

Inactive (2)

Antecedent
Data type: Win32_1394Controller
Access type: Read-only

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

Dependent
Data type: CIM_LogicalDevice
Access type: Read-only

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

NegotiatedDataWidth
Data type: uint32
Access type: Read-only

When several bus or connection-data widths are possible, this 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 or important to device management, the property should be set to 0 (zero).

NegotiatedSpeed
Data type: uint64
Access type: Read-only

When several bus or connection speeds are possible, this property defines the one being used 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 or important to device management, the property should be set to 0 (zero).

NumberOfHardResets
Data type: uint32
Access type: Read-only

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
Data type: uint32
Access type: Read-only

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