    I’m having the same problem with my keyboard. But I’m pretty sure the problem is my keyboard and not my pc. Cause I tried connecting my keyboard to two different PCs and both of them said Unknown USB. Do you have any suggestions on how to fix that?

    You need to be mindful of the fact that there are 30 fucking thousand different versions of Windows 10 that all work different. This helps no one because the version you are using no longer exists. Never make a video again.

    After months of my desktop spontaneously deciding it no longer wanted to serve power to my USB devices leading to several clean installs of Windows and a 4-month decommissioning, I was able to plug in my kb/m through an USB-C plug in the back, followed this tutorial and it worked!! I searched everywhere on the internet for a solution and couldn’t find one until your video. Thank you so much, again! You saved my life!!

    Every fucking time Windows 10 updates, there's a problem that needs of someone's attention and time. This fucking product is ADD AF! I'm really frustrated with Microsoft.

    Wow! It was that simple huh, I'm a computer engineer with 16 years of experience and I couldn't even fix this shit.
    I downloaded USBDeview because I was constantly getting a usb disconnect sound randomly throughout the day. I tried fixing it every way I knew how, turns out all I had to do was disablen the USB selective suspend setting in the power settings. I gotta start thinking more basically instead of going all elaborate. Thanks for the help bud.

    had this problem for over a year. It takes out over half my ports now and has been getting worse nothing has fixed it and the problem just comes and goes. Better yet with my windows 10 there is NO hardware troubleshooting where everyone says
