pi does not automatically mount homeduino on /dev/ttyUSB0 #26

When I reboot my pi the serial interface is unavailable, I have to physcially remove and insert the USB cable to make my pi recognize the arduino/homeduino. Is there a solution to this?

Maybe the OS assigns another device id on reboot. Please check if you see any usb device after reboot (before removing and inserting the usb cable).

ls /dev/ttyUSB*
dmesg | grep usb

i have the same issue. if i shutdown the raspberry with the homeduino connectet via USB, the raspberry dit not find it.

i must just shutdown the raspberry, unplug the homeduino, restart the raspberry, stop Pimatic, plug in the homeduino, start pimatic.

This is my workaround. HW: Raspberry Pi B+ and Raspberry Pi3 both the same issue.

The following hint should solve the issue. Re-open otherwise
