I think this two devices are cheap China Arduinos they have the same Chipset and also the same serial-no. I have the same problem… so the Raspberry don’t know who is USB0 and who is USB1 and at every reboot the USB-Port changed…
I haven’t solved the problem jet. I have ordered some Arduinos from an other seller and hope this solved this.
