My target hardware will be a USB DEVICE using the xmc4500.
I am using the USBVC001 Virtual comm port App.
I have 2 questions...

I am using the USBVC001 Virtual comm port App.
I have 2 questions...
- Must I connect the xmc4500 'USB ID' signal (P0.9) to my USB connector pin 4 or can I use P0.9 for another function (like U1C1.SELO0) ?
- Can the USB connector pin 4 be left open circuit ?
Best regards
Aaron

Answered my own question.
USB DEVICE functions correctly using USBVC001 without the 'USB ID' pin (P0.9) connected.
Pin 4 (ID) on connector can also be left open circuit.
Pretty sure P0.9 can now be used for another function but have yet to test that.

Hi Aaron,
Just to ensure you that the Pin P0.9 can be use for other function.
Suppose the P0.9 is used for USB ID which will determine whether to work as host or device mode for USB OTG mode.
Since our App only provide either Host mode or Device mode, we have configured the mode in the low level driver and it is no longer depends on the USB ID pin.
