No Response Or Notification When Usb Cable Is Connected To The Pc

Jun 19, 2016
Hi, I have a RedMi Note 3. When I connect the phone via a USB cable into the PC, I usually got a notification icon (and a slider switch) from the phone screen. The Mi PC Suite in the PC could also detect the phone connection. Yesterday this no longer happened. The notification icon from the phone screen is missing and the Mi PC Suite no longer could sense the USB connection. However, the orange LED indicator on the top right corner of the phone and the phone screen did light up after the USB connection to the PC. I rebooted the phone several times, tried other USB cable and USB ports, and still the problem persisted. Can anyone help me to resolve this problem?
