Win32_USBControllerDevice class

The Win32_USBControllerDevice association WMI class relates a universal serial bus (USB) controller and the CIM_LogicalDevice instance connected to it.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.

Properties

The Win32_USBControllerDevice 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.

This property is inherited from CIM_ControlledBy.

Unknown (0)

Active (1)

Inactive (2)

Antecedent
Data type: CIM_USBController
Access type: Read-only
Qualifiers: key, Override ("Antecedent"), MappingStrings ("CIM|CIM_USBController")

A CIM_USBController representing the Universal Serial Bus (USB) controller associated with this device.

Dependent
Data type: CIM_LogicalDevice
Access type: Read-only
Qualifiers: key, Override ("Dependent"), MappingStrings ("CIM|CIM_LogicalDevice")

A CIM_LogicalDevice describing the logical device connected to the Universal Serial Bus (USB) controller.

NegotiatedDataWidth
Data type: uint32
Access type: Read-only
Qualifiers: Units ("bits")

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).

This property is inherited from CIM_DeviceConnection.

NegotiatedSpeed
Data type: uint64
Access type: Read-only
Qualifiers: Units ("bits per second")

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).

For more information about using uint64 values in scripts, see Scripting in WMI.

This property is inherited from CIM_DeviceConnection.

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.

This property is inherited from CIM_ControlledBy.

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.

This property is inherited from CIM_ControlledBy.

Remarks

The Win32_USBControllerDevice class is derived from CIM_ControlledBy.
