    Unknown device in Device manager

    martin_mortensen

      When I plug in the Galileo it shows up as Unknown device in device manager.  The Getting Started guide says to confirm that usbser.sys is missing and fix that.  But in my case the file is there.

       

      I tried installing the driver with the "the let me pick from a list" option but the install fails and I get an error "Windows has stopped this device because it has reported problems (Code43)"  Now it's showing up in device manager as Arduino but with the yellow Exclamation point and the port doesn't show up in the Arduino GUI.

       

      I don't think it's a bad cable because if I plug the same cable into an arduino it is recognized fine.

       

      Any ideas how to fix this?
