I have found a very similar issue to me mine in this thread: Link
Tho’ it’s juts a “hacking” solution, but no better given (that I could know at the moment), I would try the trick mentioned there to modify the usbmount.conf file, but in my case there’s no usbmount.conf file at all on the Volumio’s SD card anywhere (tho’ it is likely supposed to be in the etc/usbmount folder, that is also missing in my case). I have searched through the whole file system with WinSPC from Windows through SCP connection for both the folder and the file, but ended up with no results. (Maybe it’s because the new 3.xxx version of Volumio uses a different config file logic, but at this point I’m helpless here on my own). Any tips you have that what could be the catch here and what else I could to try in my case?
