workable example for CONFIG_USB_OHCI_HCD and CONFIG_USB_OHCI_GENERIC (usb kbd on usb2.0 port)
kedge# usb tree USB device tree: 1 Hub (480 Mb/s, 0mA) u-boot EHCI Host Controller
1 Hub (12 Mb/s, 0mA) | U-Boot Root Hub | +-2 Human Interface (1.5 Mb/s, 100mA) Dell KB216 Wired Keyboard
1 Hub (480 Mb/s, 0mA) u-boot EHCI Host Controller
1 Hub (12 Mb/s, 0mA) U-Boot Root Hub
1 Hub (5 Gb/s, 0mA) U-Boot XHCI Host Controller
and for usbkbd connected to usb3 port
kedge# usb tree USB device tree: 1 Hub (480 Mb/s, 0mA) u-boot EHCI Host Controller
1 Hub (12 Mb/s, 0mA) U-Boot Root Hub
1 Hub (480 Mb/s, 0mA) u-boot EHCI Host Controller
1 Hub (12 Mb/s, 0mA) U-Boot Root Hub
1 Hub (5 Gb/s, 0mA) | U-Boot XHCI Host Controller | +-2 Human Interface (1.5 Mb/s, 100mA) Dell KB216 Wired Keyboard
PS: usb2.0 port cant recognize any usb1.1 devices without OHCI

yes i know it !
for example some other rk3399 boards have it because (usb 1.1 didnt work without ohci on usb2.0 port and not possible to use usb kbd for this port )
grep CONFIG_USB_OHCI_GENERIC configs/*3399* configs/pinebook-pro-rk3399_defconfig:CONFIG_USB_OHCI_GENERIC=y configs/rock960-rk3399_defconfig:CONFIG_USB_OHCI_GENERIC=y configs/rockpro64-rk3399_defconfig:CONFIG_USB_OHCI_GENERIC=y
many other boards which used TARGET_EVB_RK3399=y must have same problem (with usb1.1)
and i think other boards must have possibilities to use CONFIG_USB_OHCI_HCD and CONFIG_USB_OHCI_GENERIC.
grep EVB configs/*3399*

Add missed definations.
But , evb_rk3399 board does not enable CONFIG_USB_OHCI_HCD and CONFIG_USB_OHCI_GENERIC.
Thanks,
