Orangecube connection problem with qgroundcontrol

Hi everyone;

I downloaded the latest version QGC from but the orange cube is not connecting to QGC via usb.

I can connect with mission planner.
It is possible to connect with the telemetry module
I have already tried 2 different USB cable but not connect

this problem only occurs when ardupilot firmware is installed. When I install the px4 firmware, it connects with a usb cable without any problems.

do you have any idea?
