Advanced Usb Port Monitor 2.3.0.14 The USB Ports + Card Reader On My Dell Monitor Suddenly Stopped Working, What Could Be The Cause Of This?

The USB ports + card reader on my dell monitor suddenly stopped working, what could be the cause of this? - advanced usb port monitor 2.3.0.14

There are about two days, well-functioning USB port and card reader on my widescreen monitor from Dell. I turned on my computer the next day and realized that the two USB ports and card reader does not recognize a device connected. I have two USB ports and a card reader at the front of my CPU and works well. Is there a solution for this problem?

Thanks in advance
