A priori nothing special to report on the USB OTG cable. It has a micro USB plug and a USB socket It worked the first time with paid app 'Nexus Media Importer.' ' This compensates for the lack of the Nexus card reader. It is used with a Google Nexus 7 Tablet (2013), without any changes, it can read RAW files (CR2 or Nef). Sometimes a bit slow to open some photo files rather 'heavy' (original Nikon D 600). Very pleased with this configuration that will allow me to view my pictures at trip a little more comfortably with the screen of my SLR. And possibly see movies, all formats with VLC. A counselor and use with Nexus Media Importer.
