ADB ONLY SOLUTION

Seem like as of now USB drives aren't mounted automatically. In order to make your code work I had to mount it manually.

As you can see (from /proc/partitions) in the /proc partition the USB drive is detected as sda.

ADB mounting

• Make a directory to mount to

  mkdir /mnt/usb
  

• Mount the device

  mount -t vfat -o rw /dev/block/sda1 /mnt/usb
  

Now you should be able to list (and manage) the files on the USB drive both via ADB and from within the app (/mnt/usb will also be logged).
