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.

Syntax

[Provider("CIMWin32a"), Dynamic]class Win32_ControllerHasHub : CIM_USBControllerHasHub
{
  uint16                  AccessState;
  Win32_USBController REF Antecedent;
  Win32_USBHub        REF Dependent;
  uint32                  NegotiatedDataWidth;
  uint64                  NegotiatedSpeed;
  uint32                  NumberOfHardResets;
  uint32                  NumberOfSoftResets;
};

Members

The Win32_ControllerHasHub class has these types of members:

Properties

The Win32_ControllerHasHub class has these properties.

AccessState
Data type: uint16
Access type: Read-only

If True, the controller actively commands or accesses 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.

ValueMeaning
0

Unknown.

1

Commanding or accessing device.

2

Not commanding or accessing device.

 

Antecedent
Data type: Win32_USBController
Access type: Read-only
Qualifiers: Key, Dynamic, Min (1) , Max (1)

Reference to an instance that represents the USB controller. This property is inherited from CIM_Dependency.

Dependent
Data type: Win32_USBHub
Access type: Read-only
Qualifiers: Key, Dynamic, Min (1)

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
Qualifiers: Units (Bits) , Dynamic

Bus or connection data width in use between devices, when several bus or connection data widths are possible. If data width is not negotiated, or if this information is not available or important to device management, the property must be set to 0 (zero). This information is necessary when a logical device can be commanded by, or accessed through, multiple controllers. This property is inherited from CIM_DeviceConnection.

NegotiatedSpeed
Data type: uint64
Access type: Read-only
Qualifiers: Units (Bits per second) , Dynamic

Bus or connection speed in use between devices, when several bus or connection speeds are possible. If connection or bus speeds are not negotiated, or if this information is not available or important to device management, the property must 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. This property is inherited from CIM_ControlledBy.

NumberOfSoftResets
Data type: uint32
Access type: Read-only

Number of soft resets issued by the controller. This property is inherited from CIM_ControlledBy.

Remarks

The Win32_ControllerHasHub class is inherited from CIM_ControlledBy.
