[EDIT: problem solved. It was a lose connection. On to the next problem I can't solve . . . thanks to anyone who contemplated my problem.]
I am having this exact same problem, but I'm at a lost as to how to 'fix' it.
I run the scanner and get no devices found. I switch the connection to go to the board's dedicated SCL and SDA slots, but it didn't fix it.
I'm really at a loss, any thoughts, ideas or suggestions would be really appreciated.
I am very much a noobie at all this.
could it be as simple as a loose connection?
Some pictures of the setup:
