Issue Connecting the Mavic3 with E-Port

[JaMateoslu]

The E-Port is connected as well as a data communication cable from USB-C to USB to enable the PSDK but I am unable to see it on my Laptop.
I am running Ubuntu 22.04 with ROS2 Humble installed.

The drone is connected but it cannot be seen on any of the USB Ports when calling the following method:

javibuntu@javibuntu-Thin-GF63-12VE:$ ls /dev/usb-ffs/
ls: no se puede acceder a '/dev/usb-ffs/': No existe el archivo o el directorio
javibuntu@javibuntu-Thin-GF63-12VE:$ ls /dev/ttyACM*
ls: no se puede acceder a '/dev/ttyACM*': No existe el archivo o el directorio
javibuntu@javibuntu-Thin-GF63-12VE:~$

Only when listing the devices is when it appears but cannot be mapped as mentioned before, thus the warpper cannot be initialized.

When tryin to find the serial port I am unable to do so:
javibuntu@javibuntu-Thin-GF63-12VE:~$ ls /dev/ttyUSB* /dev/ttyACM* /dev/serial/by-id/*
ls: no se puede acceder a '/dev/ttyUSB*': No existe el archivo o el directorio
ls: no se puede acceder a '/dev/ttyACM*': No existe el archivo o el directorio
ls: no se puede acceder a '/dev/serial/by-id/*': No existe el archivo o el directorio

This is the hardware connection of the drone with the SDK according to the documentation.

Drone Mavic 3T --> E-Port + Computer

Have tried with different cables USBC to USB and USBC

The E-Port Development Kit light turns greens but dissapears after a couple seconds unless I press it hard against the E-Port.

Agent comment from LIPING.ZHOU in Zendesk ticket #128359:

Dear Developer,

Hello and thank you for reaching out to DJI Innovations.

Check the connection: Ensure that the E-Port development kit is securely connected to the aircraft without any looseness.

Measure the voltage: Use a multimeter to measure the voltage output of the E-Port expansion board and confirm that it is stable.

Check the DIP switch: Ensure that the DIP switch is in the ON position and has not been accidentally switched to the OFF position.

Here is the relevant documentation link:PSDK各机型连接(M350/M300/M30/M30T/M3E/M3T/M3D/M3TD)

We hope that our solution meets your needs satisfactorily. We appreciate your email and wish you a wonderful day!

Best Regards,
