Yeah the distinction is between host vs client mode. If you are plugging the device into something else (e.g. computer) and using it on than something else, it will work fine. On the other hand, if you want the N900 to act as a host--to plug something into N900 and use it on N900--it won't.

Except on the off chance that OTG is supported after all. After reading a lot of this thread, i really think that horse has been dead and beat into the ground and people are now just beating the ground.
