USB 3.0 -- device/peripheral mode?

I’m very interested in this device for an application that requires “super speed” USB 3.0 in device mode, but before I commit to spending any money on one, I need to know if the USB 3.0 port can be configured like that? I’m already aware that I’ll have to jump pin 1-5 on U8507 to power it from the USB 3.0 port.

The datasheet says this;

Dual USB 2.0 high-speed USB I/O, one USB Host and one USB OTG
• One USB SS and PCIE 2.0 combo interface up to 5Gbps, supporting 2 configurations:
o 1 USB2.0 OTG + 1 USB 2.0 Host + 1 PCIe
o 1 USB2.0 OTG + 1 USB3.0 (No PCIe)

That is, unfortunately, not clear about whether or not the USB 3.0 supports device mode.

On the wiki page
USB 2.0 OTG X1, shared with USB power
USB 3.0 HOST X1 in USB C type

Only the 2.0 OTG controller can be USB device/host mode. USB3.0 supports host mode.
