Hello,
You may have a problem in the schematic but also in the PCB that makes the device to don't work properly. I will have to see the schematic
I am not from North America but I think we can work something out.
About Me:

- USB charging - accelerometers, gyroscopes
- GPS and GSM - LCD Displays
- LED power calculation
As a Layouter I have 5 Years experience. I am an expert in
: - Power Dissipation Calculation
- EMC Rules - Impedance Calculation
- Manufacturing Rules I have made Layout for ARM processor. Work also with BGA footprint. I have done projects even on 10 layer. So I know how to build a layer stack up.
As Layout and Schematic software I am an expert in Eagle, PADs, Zuken.
As Simulation software for the Schematic I used LTSpice.
Thank you for your time,
Have a Nice Day,
