PS2, Line 24: 		config->usb2_ports[6].enable = 0;
            : 		config->usb2_ports[6].ocpin = OC_SKIP;
            : 		config->usb2_ports[6].tx_bias = USB2_BIAS_0MV;
            : 		config->usb2_ports[6].tx_emp_enable = USB2_EMP_OFF;
            : 		config->usb2_ports[6].pre_emp_bias = USB2_BIAS_0MV;
            : 		config->usb2_ports[6].pre_emp_bit = USB2_HALF_BIT_PRE_EMP;
Can you try this?

```suggestion
    	config->usb2_ports[6] = (struct usb2_port_config) USB2_PORT_EMPTY;
```
