To support this mode, the driver must limit the speed programmed into the DCFG register to Hi-Speed or lower. Reads and writes to the PIPECTL register are left as-is, since they should be no-ops in USB 2.0-only mode. Calls to phy_init() etc. for the USB3 phy are also left as-is, since the no-op USB3 phy should be used for USB 2.0-only mode controllers.
