It's a udev rule which might be too general. You'll need to set USBAUTO=true in /etc/sysconfig/gpsd to disable starting gpsd from udev. *** This bug has been marked as a duplicate of bug 663124 *** |
Description of problem: When the system boots, gpsd opens some of my USB serial ports and doesn't let them go. I have 6 serial ports that I use for communicating with my test machines: warthog>lsusb | grep FT232 Bus 002 Device 009: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 002 Device 010: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 002 Device 014: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 002 Device 015: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 002 Device 023: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 002 Device 024: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC However, they match a rule in /etc/udev/rules.d/99-gpsd.rules and so start up gpsd. Version-Release number of selected component (if applicable): gpsd-2.95-6.fc15.x86_64 How reproducible: 100% Steps to Reproduce: 1.Boot the system or: 1.Kill gpsd. 2.Unplug and plug back in the USB serial port adapters.

Additionally, querying systemd with "systemctl --all | grep gps" shows: dev-gps0.device loaded active plugged FT232 USB-Serial (UART) IC dev-gps1.device loaded active plugged FT232 USB-Serial (UART) IC dev-gps2.device loaded active plugged FT232 USB-Serial (UART) IC dev-gps3.device loaded active plugged FT232 USB-Serial (UART) IC dev-gps4.device loaded active plugged FT232 USB-Serial (UART) IC dev-gps5.device loaded active plugged FT232 USB-Serial (UART) IC though I've no idea why that thinks they're GPS ports - presumably something to do with udev.
