Through USB.

I just tested with standard i2c library and its the same problem. TEENSY41_NE does not work and TEENSY41 works fine with same code. Here is the code. I made change to look for any byte available from Wire2 instead of...

I think the wire library supplied by PJRC in Teensyduino does not support wire2. At least thats what my understanding is from the table in Hardware requirements section at https://www.pjrc.com/teensy/td_libs_Wire.html....

Here it is. I downloaded this exact program in to two different boards one with TEENSY_41 and other with TEENSY41_NE. TEENSY41 prints some ADC reading and does not print the error message. TEENSY41_NE prints only error...
