We observe that without anything attached, the resistance between pin 11 and 12 is exactly 200Kohm. When the DevKit USB ethernet adapter is plugged in, the resistance between pin 11 and 12 is non-linear. One theory is that there is some sort of accessory sense based on these pins and the [[Ernie_Firmware#Voltage_Table]]. | We observe that without anything attached, the resistance between pin 11 and 12 is exactly 200Kohm.
