Qgc on Android doesn't connect to pixhawk cube via usb

Qgc on Android doesn’t connect to pixhawk cube via usb. Error on link serial device on. Error connecting: Could not create port.
I’m using Xiaomi redmi note 8 pro (Android 10qp1a, MIUI global 12.0.4) qgc v4.1.1 64bit

Console: [D]at/home/travis/build/mavlink/qground control/src/comm/LinkManager.cc.466:“Skipping serial port list”

Everything is working when I’m using mission planer

Hi, did you find a solution? I have the same Problem now. Thanks. Mathias
