And I've seen instances where if the device has not yet been recognized it will not pick up the device theough a usb 3.0 link. So maybe first get your note recognized by using a 2.0 connector then backdoor with the 3.0 and see what happens.
samsung test all of their cords before they leave manufacturing so getting a dud is very unlikely yet not impossible.
As for the aftermarket cords I normally stick to belkin. Best build quality for a fair price.
I have tried everything.
I plugged into 2.0 and the 3 options pop up to select a mode where 3.0 is grayed out. That menu closes when you unplug.
If you lock your phone while in this menu, you can change the port, unlock the phone and the menu is still there, but it will not allow me to select 3.0.
I have 2 3.0 ports on my laptop, 1 on the docking station, and 1 on my standalone.
None of them work with the aftermarket cable. I will take it as a loss as I really only need them for charging away from home.
