USB ports not reading anything

Hello, I recently bought a USB wifi adapter to connect to the internet however when I try to plug it in to USB port on the back of my pc it is not recognized. This goes for all available USB ports. Additionally, upon initially turning on my pc the mouse and keyboard will work fine. But if I unplug and plug back in they are no longer recognized. The odd thing is if I hardwire internet with an Ethernet cable everything works fine and the wifi adapter is recognized and I can establish a wifi connection. This problem only occurs when I don’t have internet to start with. Lastly, whenever I try to restart my pc it takes an unusually long time and I will get a blue screen error “driver_power_state_failure”. Any help figuring out why this is happening would be greatly appreciated.

    Hello,

    Thank you for posting in Microsoft Community forum.

    Based on the description, I understand your question is related to USB ports not reading anything.

     1. The DRIVER_POWER_STATE_FAILURE bug check has a value of 0x0000009F. This bug check indicates that the driver is in an inconsistent or invalid power state. Try trouble shoot using below link:

    1. Update your USB wifi adapter, also try go back to previous version of the driver before this issue happen.
    2. Open Device Manager/ Network adapters, right-click on your external USB Wi-Fi adapter and select Properties.

    Go to the Power Management tab and uncheck “Allow the computer to turn off this device to save power”.

    1. Control Panel > Hardware and Sound > Power Options > Choose what the power buttons do > Change settings that are currently unavailable > Uncheck “Turn on fast startup”.
    2. Boot your PC in Safe Mode and see if the USB Wi-Fi adapter is recognized. If it works in Safe Mode, there might be a software conflict causing the issue.

    Have a nice day.
