After every single Windows update, in Device Manager 1) USB controllers and 2) Human Interface Devices...Properties | Power Management all change back to "allow the computer to turn off this device to save power". About 20 each in 1) and 2). What fun to manually uncheck all those boxes marked "allow the computer..."

If I don't, then right after every windows update I get 3 to 10 second pauses in flight and the tell tale sound (BeeTelBeep) of USB doing its off then right back on thing. Then I go uncheck those boxes in device manager and all is well again. Until the next Windows update in a few weeks. (Sigh).

I can't really comment on your problem, I've never experienced your described problem, but I still have a question, if I may?  If you uncheck all those boxes on USB devices, do they still power down when computer goes to sleep?

SOP before MSFS start is to actually disconnect any USB's aside from yoke/pedals

Have you tried to disable USB Selective suspension? 

Open the start menu, type 'power plan', click edit power plan, click 'Change advanced power settings', scroll down to 'USB settings->USB selective suspend settings'. Select disable, click apply, click OK

Thanks wims80 but selective suspend was already set to disabled, and does stay that way with Windows updates.

Unplugging USB devices doesn't help on my system. Keyboard, mouse, wifi all are USB. Windows can disable the HIDs, not just the USB ports being used, if you don't uncheck all the boxes.

I think Bob Church said in Windows XP this did not happen. CH Products controllers ruled back then.

Sorry to resserect this old post, but I have this exact problem and have to manually disable sleep mode on 20 odd devices after each update too... 

PS yoou can run this script in powershell (just copy and paste it) and it will auto disable sleep mode on all your USB devices for you.

$USBHubs = Get-WmiObject -Class Win32_USBHub
$PowerMgmt = Get-WmiObject -Class MSPower_DeviceEnable -Namespace root\wmi

ForEach ($Hub in $USBHubs) {
    Write-Host
    Write-Host -Object "Checking USB Hub '$($Hub.Name)'..."
    $VarPowerSettings = $PowerMgmt | Where {$_.InstanceName -like "*$($Hub.DeviceID)*"}
    If (($VarPowerSettings | Measure).Count -eq 1) {
        If (($VarPowerSettings | Select -ExpandProperty Enable) -eq $False) {Write-Host -Object "USB Hub '$($Hub.Name)' already has power saving disabled" -ForegroundColor Green}
        Else {
            Try {
                $VarPowerSettings.Enable = $False
                $Null = $VarPowerSettings.psbase.Put()
                Write-Host -Object "Disabled power saving features for USB Hub '$($Hub.Name)'" -ForegroundColor Green
            }
            Catch {Write-Warning -Message "One or more exceptions occurred when trying to set power saving settings for USB Hub '$($Hub.Name)'"}
        }
    }
    ElseIf (($VarPowerSettings | Measure).Count -gt 1) {Write-Warning -Message "More than one WMI object representing power settings was found for '$($Hub.Name)', no settings have been changed for this device"}
    Else {Write-Warning -Message "No power settings were found for '$($Hub.Name)', please check if the device supports power saving features"}
}

You mean you didn't have this problem before and started having it now?

I had the pauses but could never figure out what was causing them, then I started hearing very faintly in the background the usb disconnect sound. So, I researched it, and in finding the solution I stumbled across this thread, and realised he was having  the same issue. So hopefully it helps others too.

Ps I’ve had the problem for ages I just have not been simming much the last 9 months or so, too busy doing other things. 

Which USB devices usually cause this issue? I always had UBS suspend enabled and never noticed any issues of this kind.

Same here.

Further research shows that it only happens on some motherboards. So, if you don't have the issue, then you are obviously not affected. 

I was gettting this on my bluetootth trackball but it was resolved a few updates ago.

Is this Win 11, or Win 10?

11 for me but I read it happens on 10 too.
