Mounts non-hierarchical storage.

Seems to be working well, I tested on a panono camera.

I want to know what FilesystemType is in

lsusb won't tell. You have to send it a GetStorageInfo MTP request.

The easiest is to add a println to the code snippet I mentioned above.

[bezineb5]

Then the answer is "3". I hope this helps!

In the light of your remark, I'm going to update my PR to handle the DCF case properly.
