If you're using a recent version of Ubuntu/Debian, modem-manager opens
serial devices when connected and probes for a modem.
Also, on older versions of Ubuntu brltty might block the port.

To work around the modem-manager issue either uninstall it, or put a
udev blacklist rule in place (where you insert the VID/PID of your
adapter):
