I have a dual boot system with windows 8.1 and ubuntu. When I was playing games on windows my mouse suddenly lost its connection and get connected again for few times fastly. Then soon after it stopped working. All my usb ports stopped working after this. I tested my ports on ubuntu which is another operation system and all working fine. I deleted drivers from device manager and reboot my system. It automatically reinstalled my drivers but nothing has changed. I couldn't find drivers to update my usb ports manually. I use acer v3-571g.
I am also facing with some weird problems. Such as losing wireless connection when i plug off my pc from power. None of those problems happen when i use ubuntu. Thats why i am sure it is not a hardware problem. I also updated everything with windows update, again nothing happened. I don't want to reinstall windows because i had too many configurations. I am suspicious about power issues. I use a second monitor and it suddenly lost it connection few times today for the first time.
Edit: All usb ports seem to be working fine on device manager. I also wonder what is the value of power requirement should be for an unpugged usb port? Should it be 0? I have 0...
Edit2: I also unchecked the box where it says "pc can close this device to save power" something like that.
