Having fixed Garmin-babel communication some time ago I have encountered similar problem with another GPSdevice, namely MTK's BT747 logger. This time fixing the problem was simple.
I added the
following to the /etc/udev/rules.d/51-garmin.rules:
SYSFS{idVendor}=="10c4", SYSFS{idProduct}=="ea60", MODE="0666"
Vendor ID and product ID can
be figured out inspecting dmesg log:
# connect the device first dmesg | less
So my /etc/udev/rules.d/51-garmin.rules file
looks like in the following listing:
SYSFS{idVendor}=="091e", SYSFS{idProduct}=="0003", MODE="0666"
SYSFS{idVendor}=="10c4", SYSFS{idProduct}=="ea60", MODE="0666"
One
has to remember to stop/remove gps demon (gpsd).
