        <title>RAMPS 1.4 w/ MEGA not recognised in COM ports in windows 8.1?</title>
        <description> Hello,


I have a Surface Pro 2 tablet running windows 8.1 and I am trying to get repetier host to talk to my Prusa i3 with RAMPS 1.4 and Arduino MEGA 2560. 

The pc doesn&#039;t seem to recognize the printer on its usb port when i use repetier host, printrun nor arduino IDE.


Does anyone know how I can fix this?


Thanks!</description>

            <description><![CDATA[ Sounds like a problem with your Surface Pro 2 recognizing the FTDI chip on the Mega.  Have you installed the updated Arduino drivers for Windows 8.1?  Does Windows give you a device not recognized error or anything?  Does anything new pop up in Device Manager when you plug the Mega into your Surface Pro 2?]]></description>
