Our design has a RM48L952PWR connected to a TUSB1106 per the technical reference manual on the device port, W2FC.
I am running the RM48, CDC example project and when I plug the cable into a laptop, I can see the transactions on PIN 5 & 6 that are the correct polarity.
I can set breakpoints in USBDeviceIntHandlerInternal, and this function is entered 6 times when I plug in the cable.
This function also calls USBDIntHandlerProcessStateChange 3 out of 6 of the times it is called.
But, Pins 9 (TXDO), 15 (SE0O), and 33 (GZO) show no signs of life and the laptop identifies the device as unknown.
I have verified these pins are enabled in the pin mux.
I am out of ideas as to why the SW will not respond to the new host, I have not modified the example code.
Any insight would be appreciated.
