Unknown Vivado USB Port options

Hello,

I am working on a Zynq UltraScale+ ZU2EG design and I have configured USB0 for 2.0/3.0 operation (Host mode), but there are two options I can not find information on. Can someone please tell me on what "Enable HUB Port" and "Enable V Bus Port" options are for? Please refer to picture below.

Thank you

Hi @jawbone_101 ,

emio_hub_port_overcrnt -> don’t enable this port in PL – let it have the default value ‘0’ . We don’t need this currently.

This is for providing additional Overcurrent fault detection signal to USB controller for disabling it. It can also be passed through ULPI PHY.

Please check this in version 2018.2, the USB2.0 ports "Enable Hub Port" GUI option removed

Thanks & Regards

@abommera 

Are you saying that option is removed in 2018.2? Below is screenshot from 2018.3 and the option is still there.

Regardless, it seems it is not used for normal operation, so I will not enable this option.
