Windows 10: USB devices wont power on without a PC restart,

As stated in the subject line, no USB devices are recognized or powered on unless I restart my PC. I have reinstalled all USB hubs in the device manager as well as making sure windows cannot power them off automatically. Any help would be appreciated, this is getting rather annoying.


Thank you.

USB Device taking up too much power, must disconnect

Hi,

Thank you for posting in Microsoft Community.

I would suggest you to reinstall the USB drivers and check if it helps.

• Press Windows Key + X, and select Device Manager
• Expand the Universal Serial Bus Controllers section by clicking on the
  "+" sign.
• Uninstall each of the devices under the
  USB Controller section by right-clicking on each one, and then clicking
  Uninstall.
• Close the Device Manager and
  restart your computer. Windows will automatically re-install the USB controllers in your computer, without you having to do anything further. Your computer will now run USB devices properly.

Also update chipset drivers for USB for windows 10 from the manufacturer’s website.

I suggest you to run the Power troubleshooter and check if it helps.

The power troubleshooter can automatically detect and fix any incorrect power settings. Refer to these steps to run this troubleshooter:

• Type Troubleshooting in the search box.
• Click on Troubleshooting and select the
  view all option on the left pane.
• Click on Power troubleshooter and follow the prompts.
  

Hope it helps. Please reply to us with the status of the issue.

Thanks.

my comp wont recognize an external 2.0 usb hub and shows no usb 2.0 in device manager

Hi Bob,



Thank you for writing to Microsoft Community Forums.

1. What is the make and model of the computer?
   
2. Have you tried connecting on different ports?
   
3. Which version of Windows is installed on your device?
   
   
   

Refer the article Which Windows operating system am I running to provide
the details.



However, I would suggest you to follow the steps mentioned below and let us know if that helps.



Method 1

Disable/Enable quick boot Windows 10

1. Type Power Options in Start menu search and press
   Enter key to open Power Options window.
   
2. Click on Choose what the power buttons do to open System Settings window.
   
3. Click on the link named Change settings that are currently available.
   
4. Scroll down to Shutdown settings and uncheck Turn on fast startup.
   
5. Click on Save Changes, restart the device to check the status of the issue.
   

Method 2

If the USB device does not display in Device Manager, there might be a power requirement issue. Disconnect the device and perform the following steps until the device is detected:

1. Restart the computer
   
2. Connect the device and wait 5 seconds. If the device is not recognized, disconnect it and go to the next step.
   
3. In Windows, search for and open Device Manager.
   
4. Double-click Universal Serial Bus Controllers to expand the list.
   
5. Double-click a USB Root Hub, click the
   Power tab, and then click Power Properties (if it is shown).
   
   
   
   Note: The Power tab displays only in USB 2.0. There is no Power tab in USB 3.0.
   
   Devices that are attached to the hub are shown, as well as the power that they require. If the total displayed power is over 500 mA, remove the devices and use a powered hub.
   
   
   
6. Continue looking at the power properties of each USB hub. If the total Power required exceeds the Total power available for the hub, then remove a device on that hub to lower the Power required number.
   
7. Connect the device and wait 5 seconds. If the device is not recognized, disconnect it and go to the next step.
   
8. Remove high-speed USB cables that are over 3m (9.8 ft) in length and use high-speed cables that are shorter than 3 m.
   Only use high-speed cables shorter than 3m in length with high-speed USB devices (multifunction printers, scanners, and cameras).
   
9. If the USB device is connected to a USB port on a keyboard, disconnect it, then connect it to a USB port on the computer or to a powered hub.
   
10. There might be an issue with the USB port. Try connecting to a different USB port. If the USB device displays in Device Manager after connecting the cable to a different port, then uninstall and reinstall the USB device software
    driver.
    
11. There might be an issue with the USB port. Try connecting to a different USB port. If the USB device displays in Device Manager after connecting the cable to a different port, then uninstall and reinstall the USB device software
    driver.
    
12. Consult the manufacturer of the device for support if the device still fails to display.
    

Hope it helps.
