Hi different person asked me : I have had a problem with my computer USB devices for quite some time. I have changed the computer up to the motherboard because of it, but it helped. USB- or a mouse, the keyboard and the PS4 controller there is nothing wrong with that because they function normally in other devices. Or USB devices will stop suddenly and randomly working notification sound. In order to get USB devices working again, I have to restart my computer again the power button. that a very special question Motherboard: MSI B360M PRO-VD/Hard Drive: 931GB TOSHIBA HDWD110/As I said, my only USB device is a keyboard, mouse and PS4 driver. They are connected directly to the back of the system boart. To say the tedious thing about the emergence of this machine is not connected to a grounded plug.The question would be to make it possible for usb to tease today if the devices were already protected from rubbing electricity? Sorry sorry for seeing myself thank you for your patience.
