Hm, it's pity. So, there is at least one additional bug somewhere... :-(

Maybe the problem is somewhere in root port ownership change between 
EHCI-OHCI. Unfortunately I cannot test/debug such case, I have no PC 
with EHCI-OHCI combination.
I tested root port ownership change only on EHCI-UHCI PC - it works well.
Additionally I tested connection of USB keyboard to OHCI root port on PC 
with OHCI-only USB controller - it also works well.

Could You test if Your keyboard will work on fuloong when You use only 
OHCI module (don't include/load EHCI module in GRUB)?
(EHCI module is not needed for USB keyboard in the case when keyboard is 
connected to root port - and it is Your case, according to Your lsusb 
output.)

BR,
