# Object: make sure GPS dev (ex: /dev/gps-usb) dont change name on sleep/wakeup
# -----------------------------------------------------------------------------
#
# 1) place this file in /etc/udev/rules.d
# 2) use default config or update with your own vendor:product ID (use "lsusb" to find them)
# 3) reload udev with "/etc/init.d/udev reload"
#
# Device alias can be:
#  (default) - by path  ==> SYMLINK="serial-$env(ID_PATH)"   /dev/gps-pci-0000:00:1d.1-usb-0:1:1.0
#            - static   ==> SYMLINK="gps-usb"                /dev/gps-usb
#            - custom   ==> RUN+="/usr/local/bin/myscript"   /dev/any-thingk-you-want
#
# DEFAULT CONFIG: you can use this file "as it is", you should then see a /dev/gps-pci* 
# that will be created for any of the serial/usb you hot-plug. The name is fixe but
# depend on the USB port you use. As a result the name is fix until you keep the same socket.
#
# -----------------------------------------------------------------------
# check "man 7 udev" for forther syntax. (search for %n)
# -----------------------------------------------------------------------

# Examples
# -----------------------------------------------------------------------
# Your own script:     SUBSYSTEM=="tty", ATTRS{idVendor}=="xxxx", ATTRS{idProduct}=="yyyy", RUN+="/usr/local/bin/myscript"
# Static device name:  SUBSYSTEM=="tty", ATTRS{idVendor}=="xxxx", ATTRS{idProduct}=="yyyy", SYMLINK="gps-usb"
# Path dependent name: SUBSYSTEM=="tty", ATTRS{idVendor}=="xxxx", ATTRS{idProduct}=="yyyy", SYMLINK="gps-$env{ID_PATH}"
# In first case you do what ever you want, script receive the information about context in environement variables
# In second case you name is fixe (ex: /dev/gps-usb) this is working if your usb/serial ID(vendor:product) is unique
# In third case your device name depend on the port it is plugged in.


# ========================================================================================
#                          update YOUR CONFIG here after
# ========================================================================================

# Default rules is applied for any unspecified vendor:product devices
# -----------------------------------------------------------------------------------------
SUBSYSTEM=="tty", ATTRS{idVendor}=="?*", ATTRS{idProduct}=="?*", SYMLINK="gps-$env{ID_PATH}"

# Well known device may get a static device name 
# -----------------------------------------------------------------------
SUBSYSTEM=="tty", ATTRS{idVendor}=="10c4", ATTRS{idProduct}=="ea60", SYMLINK="ttyGPS-usb"
SUBSYSTEM=="tty", ATTRS{idVendor}=="067b", ATTRS{idProduct}=="2303", SYMLINK="ttyGPS-rt650"
SUBSYSTEM=="tty", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5740", SYMLINK="ttyGPS-ait2000"
