Current status of the object. Various operational and nonoperational statuses can be defined. Operational statuses include: "OK", "Degraded", and "Pred Fail" (an element, such as a SMART-enabled hard disk drive, may be functioning properly but predicting a failure in the near future). Nonoperational statuses include: "Error", "Starting", "Stopping", and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is online, yet the managed element is neither "OK" nor in one of the other states.

This property is inherited from CIM_ManagedSystemElement.

Values include the following:

OK ("OK")

Error ("Error")

Degraded ("Degraded")

Unknown ("Unknown")

Pred Fail ("Pred Fail")

Remarks

The Win32_USBController class is derived from CIM_USBController.

You can use the Win32_USBControllerDevice association class to determine which logical devices are associated with the controller.

Examples

The following VBScript sample returns information about all the USB controllers found on a computer.

On Error Resume Next 
 
strComputer = "." 
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
