Property Description
the values in the RequestedState enumeration. Unknown (0)
indicates the last requested state for the element is unknown.
NOTE: The value No Change (5) has been deprecated
instead of indicating the last requested state is Unknown
(0). If the last requested or desired state is unknown,
RequestedState should have the value Unknown (0), but
may have the value No Change (5). There are two new
values in RequestedState that build on the statuses of
EnabledState. These are Reboot (10) and Reset (11).
Shut Down requests an orderly transition to the Disabled
state, and may involve removing power, to completely
erase any existing state. The Disabled state requests an
immediate disabling of the element, such that it will not
execute or accept any commands or processing requests.
This property is set as the result of a method invocation
(such as Start or StopService on CIM_Service), or can be
overridden and defined as WRITEable in a subclass. The
method approach is considered superior to a WRITEable
property, because it allows an explicit invocation of the
operation and the return of a result code. If knowledge
of the last RequestedState is not supported for the
EnabledLogicalElement, the property is NULL or has the
value 12 Not Applicable. Possible values are:
● 0 = Unknown
● 2 = Enabled
● 3 = Disabled
● 4 = Shut Down
● 5 = No Change
● 6 = Offline—Indicates that the element has been
requested to transition to the Enabled but Offline
EnabledState.
● 7 = Test
● 8 = Deferred
● 9 = Quiesce
● 10 = Reboot—Refers to doing a Shut Down and then
moving to an Enabled state.
● 11 = Reset—Indicates that the element is first Disabled
and then Enabled.
● 12 = Not Applicable
● .. = DMTF Reserved
● 32768..65535 = Vendor Reserved
Speed
USB Port Speed in bits per second. This speed is determined
and set by the attached Device. The attached Device is
indicated using the USBConnection association. At this time,
only several Port speeds are valid. These are: 1.5Mbps and
12Mbps. The value 0 can also be specified to indicate that the
current speed is unknown or 1 to indicate that the speed is
other than 1.5 or 12Mbps. Possible values are: 0, 1, 1500000,
12000000
SystemCreationClassName The CreationClassName of the scoping system.
SystemName The System Name of the scoping system.
TransitioningToState Indicates the target state to which the instance is
transitioning. Possible values are:
