I have a bunch of Arduino hardware that connects with emulated serial ports using FTDI chips (there are other possibilities for serial port emulation too, e.g. CP2102 or microcontroller based ones).
As soon as I plug one of these devices in, modem-manager becomes active and probes the devices, timing out each time (of course) and retrying that about 3 times. This interferes with the serial port being used by Arduino or terminal software. What is the mechanism to tell modem-manager to keep its hands off FTDI-based serial ports? I have used udev rules to create constant-name device symlinks based on the devices USB IDs and serial number. I realise that modems use emulated serial ports too so there is always conflict, but I am not sure whether there are modems using devices for which the device name is /dev/ttyUSBN. I'd be happy to configure exclusion lists, but how do I do this? There also seems to be a difference between desktop and laptop computers. Modem-manager activates only on the laptop.
