Defines the desired power state for a logical device and when a device should be put into that state. Not implemented by WMI. This method is inherited from CIM_USBHub.
Example
Do not run below example code just to see what happens next. Many methods seriously affect your system. Always make sure you actually understand what the method and the code do.
# define the arguments you want to submit to the method
# remove values that you do not want to submit
# make sure you replace values with meaningful content before running the code
# see section "Parameters" below for a description of each argument.
$arguments = @{
PowerState = [UInt16](12345) # replace 12345 with a meaningful value
Time = [DateTime](12345) # replace 12345 with a meaningful value
}
# select the instance(s) for which you want to invoke the method
# you can use "Get-CimInstance -Query (ADD FILTER CLAUSE HERE!)" to safely play with filter clauses
# if you want to apply the method to ALL instances, remove "Where...." clause altogether.
$query = 'Select * From Win32_USBHub Where (ADD FILTER CLAUSE HERE!)'
Invoke-CimMethod -Query $query -Namespace Root/CIMV2 -MethodName SetPowerState -Arguments $arguments
To run this method on one or more remote systems, use New-CimSession
:
$ComputerName = 'server12','server14' # adjust to your server names
$Credential = Get-Credential # submit a user account with proper permissions
# define the arguments you want to submit to the method
# remove values that you do not want to submit
# make sure you replace values with meaningful content before running the code
# see section "Parameters" below for a description of each argument.
$arguments = @{
PowerState = [UInt16](12345) # replace 12345 with a meaningful value
Time = [DateTime](12345) # replace 12345 with a meaningful value
}
$session = New-CimSession -ComputerName $ComputerName -Credential $Credential
# select the instance(s) for which you want to invoke the method
# you can use "Get-CimInstance -Query (ADD FILTER CLAUSE HERE!)" to safely play with filter clauses
$query = 'Select * From Win32_USBHub Where (ADD FILTER CLAUSE HERE!)'

Syntax
uint32 SetPowerState(
[in] uint16 PowerState,
[in] datetime Time
);
Parameters
Name | Type | Description |
---|---|---|
PowerState | UInt16 | |
Time | DateTime |
Return Value
Returns a value of type UInt32. Typically, a value of 0 indicates success.
Requirements
To use Win32_USBHub, the following requirements apply:
PowerShell
Get-CimInstance
was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.
If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.
Operating System
Win32_USBHub was introduced on clients with Windows Vista and on servers with Windows Server 2008.
Namespace
Win32_USBHub lives in the Namespace Root/CIMV2. This is the default namespace. There is no need to use the -Namespace parameter in Get-CimInstance
.
Implementation
Win32_USBHub is implemented in Wmipcima.dll and defined in Wmipcima.mof. Both files are located in the folder C:\Windows\system32\wbem
:
explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\Wmipcima.mof
