Description of problem: Attempting to use a FT232 USB to serial converter does not work. How reproducible: Always Steps to Reproduce: 1. log in with a user in the "dialout" group 2. connect an FT232 USB-to-serial converter 3. Attempt to open the serial port Actual results: $ picocom /dev/ttyUSB0 -b115200 [..] FATAL: cannot open /dev/ttyUSB0: Device or resource busy Expected results: Serial port works normally. Additional info: Trying to find why the resource is busy leads to gpsd $ sudo lsof /dev/ttyUSB0 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME gpsd 28540 nobody 7u CHR 188,0 0t0 17364030 /dev/ttyUSB0 Which leads to the culprit rule in /etc/udev/rules.d/99-gpsd.rules: # FTDI 8U232AM / FT232 [linux module: ftdi_sio] ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", SYMLINK+="gps%n", RUN+="/lib/udev/gpsd.hotplug"
