RISC-V new hardware is alway good news. Waiting for this ultra-performance RISC-V 64bits implementation using state of the art silicon process.

But here, has the USB controller a device mode?

what's device mode? From the datasheet: "This chip supports 1 USB interface, supports USB OTG protocol standard (USB2.0, compatible with USB1.1), and allows the device to operate as both a host and a peripheral. It can provide certain host detection capabilities, support host communication protocol (HNP) and conversation request protocol (SRP)."

Yes host and device are the standard USB system design [1] terms.
