Windows 10: A powered USB hub still leaves the green light on even after I unplug the PC?

Hi, I have an HP PC with a powered USB hub; when I turn off the PC, the green light stays on in the back of the PC, but it still stays on after I unplug the power cord. But, when I unplug the power source from the USB hub, the green light on the back of the PC goes out. I got an error when I started the PC up the other day and had to force power it down. It started back up fine, but I can't remember what the error was. Anybody have a reason for this, or can you tell me how to fix the problem?

USB HUB

Hi,

Incompatible USB hub driver is one of the possible reasons why this issue is happening. We recommend uninstalling the USB Root Hub driver and see if it helps. Follow the stepes below:

• Open Device Manager.
  
• Double-click Universal Serial Bus controllers to expand.
  
• Right-click USB Root Hub, then click Properties.
  
• Go to the Driver tab.
  
• Click Uninstall.
  
• Restart your computer.
  

Note: Restarting your computer will automatically reinstall a generic driver for your computer. Also, we suggest connecting your USB hub while performing the steps.

If the issue still persists, let's disable the USB selective suspend settings thru Power Options to resolve the issue. Follow the steps below:

• Type Power Options in the search box, then press Enter.
• Locate USB settings > USB selective suspend settings.
• Select Disable.

Keep us in the loop with the result.

 

USB Port Issue - Power Surge on Hub Port

I have no Idea, what i suggested you check is the USB ports on your computer ensure you didn't damage them. The Hub you smoked is smoked get rid of it.
You new Hub is it self-powered? if not you probably don't have enough power going to the hub to support many devices. The flash drive plug it into a port on your computer if it works then its ok and the issue is the hub. If not you can try to run chk disk on it maybe you can fix it.

 

USB Port Issue - Power Surge on Hub Port

Hi there like to update this and want advice/feedback. I bought a brand new 4 port usb hub. I connected it to the usb port where my previous 4 port usb hub is. I only had connected my usb flash drive into the 3rd slot. When i plugged this 4 port usb hub in, it did recognize it. However, after just a bit, i hear that message where its the same one where it would mean my usb flash drive is not recognize when i click on my computer and it should show the f drive. So then i thought... okay it might be my laptop usb port that is the issue. Then i connected a keyboard to one of the 4 ports. It immediately recognized it. Thus at the moment, i did not unplug the 4 port usb hub from the usb hub on my laptop. The wired keyboard connected to it works, but did usb flash drive does not recognize. However if i were to power off that specific 3rd usb hub and power it on again or if i just unplug the entire 4 port usb hub from the usb hub on my laptop and plug it back in, it would either work or you might have to do it a few times before it recognizes the usb flash drive.


So based on this, does this mean this is 100% the usb flash drive and not my laptop usb? So what would you suggest i do now? Make sure i have everything from that flash drive and format it? The thing is it does read the usb flash drive if i were to power off and power that button. These are individual buttons that light up for each usb port.
