I really would appreciate an answer
My gear is Canon Eos 5D mark 2
Tablet Samsung Tab. 2
All up do date (Firmwire)
Got the MR3040 ver 2 and upgraded with factory ver2 and then sys upgrade vers2.
Got all 3 green lights when i connect my canon to MR3040 and logged in to MR3040 thrue my Tablet.
But nothing happens in the DSLR dashbord ? It doesn't seems to find anything...
So what could be the problem?

Did you check, if USB OTG is working on the Tab?
For example with: https://play.google.com/store/apps/detai...oubshooter

Are you tapping the Networked Camera's button? Its the one with the 4 boxes and 3 lines. Tap that and give it a few seconds to get connected. I have run into this a few times and I found that closing out and restarting Dashboard fixed it. If it still isnt working then someone with more knowledge about your tablet will have to lend a hand.

Check this link out though so you know what button I'm talking about. It's #2

Connection Screen Buttons
