Two IMU not working

[josef821]

hi. i have two Arduino uno and mpu6050. i set the port in ArduinoControllers.ini ( PORT 3 and PORT 17 ). just port 3 working and port 17 not working. i check port 17 when game is running , it's not busy but port 3 is busy. i set the one controller ( ShoulderYaw and ShoulderPitch has values ) with port 3, it works . but port 17 not working even in one controller. i test port 17 in arduino serial port.it works but not working in steamvr.
