I'm using Node-red on a Raspberry Pi 3B+ with Raspbian Stretch.
I'm also using UUgear 7-port USB hub.
I connected RS232 devices with node-red-node-serialport, using the serial request node.
This is working very well.
But sometimes my USB ports disconnect, often when I plug a new device or when I touch the hardware.
They reconnect immediatly and can be found using the cmd console, but Node-red lost them and I have to restart Node-red to get them back.
Do you know how I can manage this so Node-red can fin them back ?
Thanks for your help
