I have a Raspberry Pi 3 Model B flashed with Raspbian by Etcher.io.
When I booted it for the first time , I was playing some YouTube videos and it worked fine with keyboard and mouse. However, after a restart it isn't recognizing any USB device but it booted succesfully.
Any suggestions why on first start it worked okay but now it isn't working? I tried to reinstall Raspbian on the SD card, and plugging USB devices in before boot, but this still doesn't work.
