NOTE: disk drive should be powered on (step #1) and phone/tablet powered on (step #2) before plugging Venti Ba-Cup into phone/tablet. Otherwise the USB drive may not be recognized.

(5) If using Nexus Media Importer, the app should show two panes, one for attached storage and one for internal filesystem. You can select and stream files; copy from internal storage to attached and vice-versa; delete files; etc. (6) A good way to use Venti Ba-Cup is to connect, transfer files and disconnect (and power off Venti Ba-Cup). This will save power and untether your phone/tablet from Venti Ba-Cup.
