USB Ports on Raspberry Pi

I'm using Domoticz with a Raspberry Pi, attached controllers are RFX Com tranciever on /dev/ttyUSB0, a Davis Vantage Weather Station on /dev/ttyUSB1 and a Aeotec ZW090 Z-Stick Gen5 EU on /dev/ttyACM0 via USB.
The problem I encounterd is that both USB devices does not initiliaze at reboot or startup, if I startup with one of the USB devices the connected device initialize correct and when I connect the other device it wil also initialize, the Z-stick initialize allways.

I'm using the system on a remote location so it is not possible to disconnect one of the USB devices everytime when the system has to reboot or so.

Is there a way to delay the initializing of one of the ports?

Thanks in advance, Henk

You can try this solution with some delay after reboot:
