Win32_ControllerHasHub class
The Win32_ControllerHasHub association WMI class represents the hubs downstream from the universal serial bus (USB) controller.
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_ControllerHasHub class has these properties.
-
AccessState
-
-
Data type: uint16
-
Access type: Read-only
When a logical device can be commanded by or accessed through multiple controllers, this property indicates whether the controller is actively commanding or accessing the device. This property is inherited from CIM_ControlledBy.

0
-
Unknown
-
1
-
Active
-
2
-
Inactive
Antecedent
-
Data type: Win32_USBController
-
Access type: Read-only
The USBController.
Dependent
Reference to an instance that represents the USB hub associated with the controller. This property is inherited from CIM_Dependency.
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 the data width is not negotiated, or if this information is not available or important to device management, the property should be set to 0. This property is inherited from CIM_DeviceConnection.
NegotiatedSpeed
-
Data type: uint64
-
Access type: Read-only
When several bus or connection speeds are possible, this 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 or important to device management, the property should be set to 0 (zero). This property is inherited from CIM_DeviceConnection.
For more information about using uint64 values in scripts, see Scripting in WMI.
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 with it. This property is inherited from CIM_ControlledBy.
Remarks
The Win32_ControllerHasHub class is inherited from CIM_ControlledBy.
