Difficulty: ★★☆☆☆
1. VERIFY THE CONNECTION WITH THE USB DEVICE
Connect the Garmin device via a USB cable.
The lsusb command displays information about USB buses and connected devices on your machine:
lsusb
The output should be :
Bus 001 Device 027: ID 091e:0003 Garmin International GPS (various models)
2. MAKE SURE GARMIN_GPS MODULE IS NOT LOADED
Next command should give no output
lsmod | grep gps
If it does, you have to remove the module
sudo -rm /lib/modules/*[your active kernel]*/kernel/drivers/usb/serial/garmin_gps.ko.xz
3. VERIFY THE ACCESS PERMISSIONS
Create a udev rule that gives you permission to access the device automatically when mounted:
sudo nano /etc/udev/rules.d/51-garmin.rules
In this text file, enter the following line:
SUBSYSTEM=="usb", ATTR{idVendor}=="091e", ATTRS{idProduct}=="0003" MODE="0666", GROUP="plugdev"
Now reload the udev rules:
sudo udevadm control --reload-rules
Unplug and replugin the GPS.
And recheck now the permissions
ls -al /dev/bus/usb/001/*
4. BLACKLIST THE GARMIN GPS IN THE POWER SETTINGS FILE
Add USB_BLACKLIST="091e:0003 to /etc/default/tlp :
sudo nano /etc/default/tlp
Copy-paste:
USB_BLACKLIST="091e:0003
Press Ctrl+X Enter Y
Now unplug and replug the GPS unit to allow it to be ready to receive data.
5. USE GPSBABEL TO TRANSFER DATA FROM GPS TO COMPUTER
sudo pacman -S gpsbabel
with the following configuration :
INPUT : choose the option «device» with the format «Garmin serial/USB protocol» and «usb :» as device name.
OUTPUT : choose the option «file» with the format «GPX XML». Select «file name» to give a name to your new file. Now you can click on «OK» to start the synchronisation.
The gpx file can be import in a application (for example Viking) or a website dedicated to cartography.
