Hi, valivetijaya, welcome to eTI !

I hope you have tried swapping the port ie. tried in other USB port ?
Also do you have any other USB device then please check if that USB device is working in that port. This is just to verify that there is no problem with your USB port.

If that is ok then let me know, we can work it out further.
