when you plug in a usb2.0 device, ehci controller will claim it.
If you plug in a usb1.x device, ehci will reroute it to the
companion ohci controller

for some reason, ehci does not get loaded.

If you have loaded the DDK, you should run usbconfig
script and select USBA1.0 on all USB hardware.
You should get usba10_ohci driver instead ohci
However, that is not the real problem here.

Have you checked dmesg output. any warning on usba10_ehci?

see above. you should see 2 ohci and one ehci node. Check if
usba10_ehci is in /etc/name_to_major and /etc/driver_aliases

BTW, there is no need to load the DDK unless you are really writing
a driver. S8 hw4 and s9 update 6 have the same stuff
