Virtual Machine Pixhawk Issue

General Discussion
1

Hello,
I have set up ubuntu into VMWare and installed qgroundcontol. Now I plugged pixhawk via USB and would like to start firmware upgrade. Firmware menu appears for 1 second, then I get an error:

    Found device: PX4 FMU V2
    Error: Open failed on port /dev/ttyACM0: Permission denied
    Upgrade cancelled
    ------------------------------------------
    If upgrade failed, make sure to connect directly to a powered USB port on your computer, not through a USB hub. Also make sure you are only powered via USB not battery.
    Upgrade cancelled

Any recommendation?
Thanx

Hi Sena,

Make sure that you are in the serial USB group (dialout), try to run a simple screen /dev/ttyACM0 command to see if you have permission.
