[SOLVED] tio /dev/ttyUSB0 not working ( RPi2 )

Good morning,

I am trying to install chimaera on an Rpi2.
I prepared an sdcard via chroot from my PC.
the RPi boots correctly, starts the ssh server and a working Xorg session.

But from my PC tio /dev/ttyUSB0 not working.
the PC can connect and disconnect, but no input is received by the RPi.

I prepared another sdcard by copying the image downloads.raspberrypi.org/.../2022-09-22-raspios-buster-armhf-lite.img.xz
it uses systemd as init.
tio /dev/ttyUSB0 works perfectly.

I added
T0:23:respawn:/sbin/agetty -o -p -- \u --keep-baud 115200,57600,38400,9600 ttyAMA0 vt220
in /etc/inittab.
no change, not working.

thanks
