could not open port /dev/ttyUSB0

Klipper log ends with:
mcu 'mcu': Starting serial connect
mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/ttyUSB0: [Errno 2] No such file or directory: '/dev/ttyUSB0'

When I look for the device it is detected:
[Sat Aug 12 10:39:48 2023] usb 1-1.2: USB disconnect, device number 4
[Sat Aug 12 10:40:02 2023] usb 1-1.2: new full-speed USB device number 5 using xhci_hcd

[Sat Aug 12 10:40:02 2023] cdc_acm 1-1.2:1.0: ttyACM2: USB ACM device

But there is no USB0 device only:
root@vcore-3:/dev/serial/by-id# ls -al
total 0
drwxr-xr-x 2 root root 80 Aug 12 10:40 .
drwxr-xr-x 4 root root 80 Aug 12 10:17 ..
lrwxrwxrwx 1 root root 13 Aug 12 10:40 usb-Klipper_stm32f446xx_btt-octopus-11-if00 -> ../../ttyACM2
lrwxrwxrwx 1 root root 13 Aug 12 10:17 usb-Klipper_stm32g0b1xx_btt-ebb42-11-if00 -> ../../ttyACM0
root@vcore-3:/dev/serial/by-id#

When I look in the RatOS/boards/btt-octopus-11/config.cfg it actually uses 
[mcu]
serial: /dev/btt-octopus-11


What is the "RatOS" way to fix this?
