Adapter requires device address to be /dev/ttyUSBx rather than better /dev/serial/by-id/nnnnnnn

[busy-omega]

This adapter requires in settings page serial device address to be /dev/ttyUSBx , but does not accept a
long string like /dev/serial/by-id/usb-FTDI_USB-to-Serial_FTHKWACI-if00-port0

During boot time of the Raspi4, the USB device numbering (0 or 1) are given to who comes up first.
Somtimes this could be the FTDI dongle getting USB0 first or sometimes my other connected serial device
gets USB0 first. This is leading in one running adapter (the one with by-id) but the other fails, because
device address already in use.

FYI: In my case the second connected device is:
/dev/serial/by-id/usb-silicon_Labs_Sonoff_Zigbee_3.0_USB_Dongle_Plus_0001-if00-port0
for the zigbee adapter. In settings page of that adapter it is possible to enter the linked address.

Would be fine, if the resol adapter also accepts the linked address to be seen in /dev/serial/by-id/xxx

Thank you !
