Windows 10 Need USB power shut off while in SLEEP mode

[Charles Linquist]

I have a MS SURFACE PRO (1st generation) that is left plugged in all the time. I need the power shut off to the USB port when the computer goes into SLEEP mode.
I have searched all the settings, but there is no option to turn off the USB power when in SLEEP mode.

I leave the Surface Pro plugged in all the time and I use it only to run Spotify and some other music applications, I have it set to sleep when I close the lid. The USB port is connected to a DSP which converts the signals to analog for the amplifiers. I "tap off" the USB power in the cable and feed it to a Solid State Relay that controls power to the rest of the sound system. I want to be able to shut everything down simply by closing the lid on the Surface Pro - and turn it on again by raising the lid.

I suppose it is possible that there is no hardware provision in that unit for shutting off USB power when it is plugged in, so I am hoping that there is a registry setting somewhere that will do what I want.

To control the USB power and behavior during sleep mode on your Microsoft Surface Pro, you can consider the following steps: 1. Device Manager Settings: - Open Device Manager in Windows. - Locate the USB Root Hub(s), USB Host Controller, or USB Hub in the list. - Right-click on your USB hub and select "Properties." - Go to the "Power Management" tab and uncheck the option that allows the computer to turn off the device to save power. 2. Changing Group Policy: - Press Win + R, type "gpedit.msc," and hit Enter to open the Group Policy Editor. - Navigate to Computer Configuration > Administrative Templates > System > Power Management > Sleep Settings. - Check for any settings related to USB power management during sleep mode and configure them accordingly. 3. Registry Modification (Advanced): - Press Win + R, type "regedit," and press Enter to open the Registry Editor. - Navigate to the "USB Settings" within the registry and explore the subkeys for power management settings. - Caution: Modifying registry keys can potentially harm your system if done incorrectly. Back up your registry settings or create a restore point before making any changes. 4. Third-Party Utilities: - Consider using third-party software or utilities that offer advanced power management features for USB ports. - Tools like USBDeview, NirSoft USBLogView, or USBlyzer may provide additional insights and control over USB power settings. 5. Consult Microsoft Support: - If you cannot find specific settings or registry keys related to USB power management, consider reaching out to Microsoft Support for guidance tailored to your Surface Pro model. Ensure you exercise caution when making changes to power management settings, especially in the Registry Editor. If unsure, consulting Microsoft Support or Surface Pro documentation can provide more detailed assistance in managing USB power during sleep mode.
