RM46L830: Required pins for USB device

Part Number: RM46L830
Other Parts Discussed in Thread: TMDXRM46HDK, TUSB1106, TUSB1105, RM46L852

Hello,

The RM46 technical reference manual does not specify which pins are required for USB device connection.

When running our application on the TMDXRM46HDK, we have no issues connecting via USB. 

When connecting on our own PCB with a different transceiver (the TUSB1106), we however, are unable to see any connection with our device.

In our own setup, we connect the TUSB1106 SOFTCON pin to Vcc through a 1k5 Ohm resistor. The USB_FUNC_PUENO and USB_FUNC_PUENON are not used, the pins are instead configured for eQEP2A and eQEP2B.

What pins are required for operation of the USB controller as a USB device?

I look forward to hearing from you,

Mathias
