I am facing a strange problem.
My Pixhawk when connected via USB gets detected and connects to Mission Planner perfectly.
The issue starts whenever I plug anything into the I2C port (GPS / I2C Extension etc.) the Pixhawk Board fails to get detected by the Windows 7 machine.
The USB says “UNKNOWN DEVICE”
After unplugging the I2C it again automatically get detected!
Please help me with the issue!
