Velbus : velbus.set_memo_text via /dev/ttyACM0

hello ,

i have a HA with velbus integration

the integration is via a usb-cable

i want to send memo_text to my oled gpod buttons.
but the text is not arriving on my oled.

i tested this also on a same velbus setup , but via a signum ip-device.
this worked fine.

how can i achieve the same via my usb ?
