I'm going to to that again now. Ill also upload the code to the Nextion using the SD and see if that makes a difference.You can upload to the nextion via SD but not sure about the Teensy. I've never looked into that.
Have you tried swapping the USB lines again to be sure?
Good catch, in my craziness yesterday, trying to verify power I must have missed that when I moved from the powered usb from the laptop to the battery. I just rewired it, let me test and see what happens now.Not following. You don't see 5v between the red and black at the display little micro usb board from the battery?

That looks right. The first in its own box should be 5v USB host/ client power then the two data and then two grounds. If you got the data+ - mixed up it won't damage anything. It just won't work. Just be sure to never allow 5v on any data lines as it's only 3.3v compliant.
ok thanks. Still same issue using a new teensie. The teensie button loads and unloads the driver, I hear the windows sounds. SDS does absolutely nothing. I tried just plugging the SDS into the laptop and proscan it instantly prompts for the serial connection so that eliminates the jack the SDS from the problem.It can be. Ground is ground. You can just pick one. There should be a card that came with it that shows the pinouts. The last two of the USB port are both grounds and also there is one on one of the corner pins and one in the middle along one side.
