Solved: USB Device Not Recognized In Windows

Last night I was fascinating USB Device Not Recognized error on my Windows PC. The error occurs when I plug in my pen drive in USB port. So I am trying to find information about this error and trying to do many things to solve this problem. The Error says,

“The last USB device you connected to this computer malfunctioned, and Windows does not recognize it.”
Or
“One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.”

First I have checked my USB drivers, but there is no problem with my USB device drivers. After that, I checked USB port but no problem with the USB ports because other devices are working correctly like my keyboard, wireless mouse, headphones, data cables, etc. The error occurs when I plug in my pen drive only. Also, I checked my pen drive in another PC and laptops, but it’s working correctly. After that, the next question on my mind is “motherboard,” but there is no problem with my motherboard. I also uninstalled USB device drivers, but it’s not working. But there are miracles when I removed the Power Supply plug, and my USB port is working. I’m shocked because I was trying many fixes, but it doesn’t work.
