Hi at all, good morning…
I’m trying to send (.gpx-) data in the following way to external storage:
from
FP4 with /e/os, 1.12.3
via
usb-c-adapter and otg-cable or micro-usb to usb-female or…
(i tried different settings)
to
Garmin Edge explore or a boring usb-data-stick
Unfortunately there is neither any ext. storage detected nor a charging-signal (Garmin)
coming up.
A second nearly identic FP4 was also testet negative similar to a Samsung S5 neo with naked Lineage OS 12 nightly.
Interestingly a FP2 with /e/OS 1.11.3 is working.
(no, i will not switch my FP4 to my daugthers FP2…).
Does anyone knows about this FP4-behavior?
Is there a workaround existing?
Are there some switches to get this otg-service in the deep of the settings?
Users experience of OTG seems to differ as suggested by a forum search for OTG. In your case I would first suspect the “chain” of cables you are using. Loosely speaking I think it is roughly correct that OTG, standard USB A connections, and USB C have a different “attitude” to asymmetric connection.
I once bought a USB OTG Adapter and it failed to do the job I wanted.( I often don’t throw things away,) so when I came to try to answer this thread My phone does not recognize usb stick the adapter did work as expected.
I find a storage device sold as OTG-enabled with both a standard USB A connection and a connection to fit my mobile (in your case USB-C) to “work every time”.
At first reading I did not think this could be your issue – as I know of no deep settings.
Just in case …
Use the search facility in Settings to search for USB.
Check that a suitable setting is enabled. Note settings can only be changed when a “live” USB cable is connected.
There is a further Default USB configuration. This is in Settings > System> Developer options. If Developer options are not enabled this is probably set to a sensible default.
If access to Developer options is required …
Settings > About Phone > Build Number or Version > Tap seven times
