USP Com port not found when connecting to upload sketch on Galileo

I am trying to upload sketches to a Galileo while running the SD version of Linux on Galileo with the USB cable under Windows 8.1. Windows 8.1 recognizes the connection as a CDC serial and then displays the file window for the SD card. It does not recognize connection as a COM port as it does when running the Galileo in the SPI system. Is there a way to upload the sketch using the USB to the system running on the SD card Linus image? Is there a way to upload sketches using the Ethernet port on Galileo?
