[Solved] Connect PPP to PC via USB for data transfer ?

[libresurf]

Hello,

The Tow-Boot mass storage flash works for me. I flashed Manjaro OS Beta 12 in the eMMC.

Now in normal use while running Manjaro OS Beta 12, I'm unable to connect my PPP to the PC via USB-C for transfer data.

On the PC, /var/log/syslog shows nothing when I connect the PPP via USB.

On the PPP, journalctl -f returns :

The USB device only manages power.

Do you know what I have to do to activate the USB connection for data sharing ?
Thank you in advance.
