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

class Win32_ControllerHasHub : CIM_USBControllerHasHub
{
  uint16              AccessState;
  Win32_USBController REF Antecedent;
  Win32_USBHub        REF Dependent;
  uint32              NegotiatedDataWidth;
  uint64              NegotiatedSpeed;
  uint32              NumberOfHardResets;
  uint32              NumberOfSoftResets;
};

Properties

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.

Value	Meaning
0	Unknown.
1	Commanding or accessing device.
2	Not commanding or accessing device.

Antecedent

Data type: Win32_USBController
Access type: Read-only
Qualifiers: Key, 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, 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)

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)

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.
