That's interesting that you say that an OTG cable works.
Elsewhere it's reported that the OTG ID pin is not connected in the NST.
Wrong! See later posts.
It's hard to check that since there is no easy way to probe that pin.
An OTG cable grounds that pin, but doesn't bring it out to where it could be measured.
It's still not clear if you can get host mode to work without the LED being on.
Powering would not be essential using a powered hub.
I still can't get anything to work here.
I can get the red LED on with a host command when it's first plugged into a charger.
Maybe su isn't working? It's there, but how do I check it? Neither of the switch applications seem to work.
Could you tell me what this does when you are connected to a keyboard?
