The TUSB319 chip handles the USB-C negotiation and it works fine. I verified all functions and voltages on pins with a attached and detached device. All pins work as they should but there is a pin that named DIR and is pulled up to 5V. As far as i understand it's a pin that shows the orientation of the inserted usb connector. It should change when inserting the connector. But for me it's always 5V. I have so far not figured out why. I'm not sure either what this pin is actually for more than as to be monitored by a external MCU or something.

I found a block diagram on TI homepage which i used for comparison.

Need to look more into it.
