3DR radio WIN 8.1

I can’t get WIN 8.1 to see 3DR radio comport. It sees the radio but no comport. The comport is yellowed out. My WIN 7 works fine with 3DR radio. Any help ? (HP15)

For Windows 8 you have to disable driver signing as the drivers are signed by someone that Windows does not trust. Advanced options 7 I think and reboot. Then reload Mission Planner and it should see your devices correctly.


Thanks Mike ! it is #7 and comport now ok…WCP
