Yesterday I tried to plug in my USB flash drive but there was no response. I tried another USB and it still didn't work. Then I tried it on another computer and it was just fine. Firstly, I restarted the computer which did not help. After that, I tried to disable USB selective suspend setting but it did not work either.
There are 2 working USB 2.0 ports which I use for my mouse and keyboard. The two 2.0 ports in the front and two 3.0 ports at the back are not working.
When I plugged in my phone, it showed the charge icon but I couldn't open the files manager of the phone.
I haven't tried uninstalling them in the device manager because I am not sure which ones should I uninstall.
