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.

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
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.
