Need to power off USB ports on shut down

[cjspizz]

Does anyone here have experience with the Digital Loggers IoT Relay 2? From my research (see the "PC USB Power Connection Example" section about half way down the page, I can plug my PC into the "Always ON" outlet then plug a USB cable into my PC with the other end of the USB cable connected to the relay on the power strip. With that setup, when I power on the PC, power goes to the relay from the USB port, then the relay will turn on anything plugged into the "Normally OFF" outlets (marquee lights, speaker amp, coin door, and monitor).

Unfortunately, every single USB port (rear and header) are still powered when the computer is Shut Down. That means none of the components get shut down. The power from the USB ports are constantly triggering the relay to power them. I need to figure out how to have at least one port power off when the PC shuts down.

I'm running Windows 7 with an old abit motherboard, and there's nothing helpful in the abit user manual. I'm positive the PC is not in Sleep or Hibernate. From my research, many people have suggested that unchecking the "Turn on fast startup" in Control Panel > Power Management will fix the problem. I've followed several different directions to find this setting but cannot. Does anyone have any suggestion for finding this setting in Windows 7?

Alternatively, does anyone have other suggestions for turning off a USB port when my PC shuts down?

Your problem is you are using the usb port.  Get a molex extension cable for one of your power rails inside the pc and hook it up to that.  Those rails always turn off even if the pc just goes to sleep. 

Before doing that though try every single usb port on the pc.... sometimes the motherboard is set up to where some usb ports are in standby mode for wake on keyboard and some aren't.   Also yeah, turn off wake on keyboard in your bios.

Try going to Devices and Printers. 


Right-click your device.


Properties


Hardware tab


Properties again


Change Settings


Power Management


Uncheck "Allow this device to wake the computer"




You can also get to this via the Device Manager, but things are labeled better in Devices and Printers (e.g., "Lenovo Mouse," or "Ultimarc Minipac."


I never shut my PC off, only sleep.  When it goes to sleep, for the mouse that I did this to, it seems like the device is still powered for 20 minutes or so (I can see the power light in my mouse).  But then the mouse light goes out and moving the mouse doesn't wake up the PC anymore.

I'm adding my voice to say get 5v from PC power.

Search for "Molex 4 Pin male connector" on your favourite online marketplace. For example:

They are very useful so grab a pack.

Cut some red/black wires to desired length, strip and crimp, job done.

You can also get SATA connectors that are even easier don't even need to strip and crimp wires - just push wire through the little blades, clip the top closed and cut off any excess.
