Starting Joystick

• Joystick is plugged into USB port.
• Open Terminal window. Note: CalVR and VRPN for joystick tracking will be run in separate terminal windows.
• Navigate to directory containing Joystick tracking executable.
  cd /home/neuro/CalVR/bin
• The "vrpn.xml" configuration file should already be in this directory, but if not, the most up to date file location is: "/home/neuro/CalVR/applications/vrpn_libusb_general/vrpn.xml"
• Type the following command into the terminal
  ./libusb_general_server

• There are a few possible ways that this command may not run properly.
  • If the output from the terminal indicates that the "vrpn.xml" configuration file was not found, use the following command:
    ./libusb_general_server XXX
    Where "XXX" is the absolute path to the "vrpn.xml" configuration file.
  • If the terminal output indicates that:
    libusb couldn't open USB device /dev/bus/usb/XXX/XXX
    There are two solutions that both require sudo permissions:

1. Run the previous command again as a sudo command.
   sudo ./libusb_general_server
2. Modify permissions of the USB joystick. sudo chmod a+rw /dev/bus/usb/XXX/XXX

• • • hello
