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.

Syntax

[Provider("CIMWin32")]class Win32_USBControllerDevice : CIM_ControlledBy
{
  uint16            AccessState;
  CIM_USBController REF Antecedent;
  CIM_LogicalDevice REF Dependent;
  uint32            NegotiatedDataWidth;
  uint64            NegotiatedSpeed;
  uint32            NumberOfHardResets;
  uint32            NumberOfSoftResets;
};

Members

The Win32_USBControllerDevice class has these types of members:

Properties

The Win32_USBControllerDevice class has these properties.

AccessState
Data type: uint16
Access type: Read-only

State of the controller access to 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.

Antecedent
Data type: CIM_USBController
Access type: Read-only
Qualifiers: Key

Reference to the CIM_USBController instance associated with this device. This property is inherited from CIM_Dependency.

Dependent
Data type: CIM_LogicalDevice
Access type: Read-only
Qualifiers: Key

Reference to the CIM_LogicalDevice instance connected to the Universal Serial Bus (USB) controller. This property is inherited from CIM_Dependency.

NegotiatedDataWidth
Data type: uint32
Access type: Read-only

Data width in use between devices (when several bus or connection data widths are possible). 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

Speed in use between devices (when several bus or connection speeds are possible). 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. 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_USBControllerDevice class is derived from CIM_ControlledBy.
