To access Ubuntu Touch storage from the PC I've read that I need to act on settings > storage. I feel like I'm missing something stupid, but I can't find storage in my Ubuntu Touch 14.10 settings scope (BQ Aquaris 4.5)
Edit: my goal was to expose the content of the SD card via either usb-storage or MTP over USB so that application on the desktop PC can act with them. I could use some kind of internet-based rsync to /media/user/something
, but that sounds like hunting goldfish with a harpoon!
