all combined (EHCI + {O,U}HCI) ports are by default owned by the EHCI
controller. You need at least a small stub (like the one in current
mainline) to give up control of the ports.

I'd ask for a bit more time :)
If you are considering earlier integration, these are the options:
a) merge everything but EHCI changes, the stub will continue to do it's
job and everything should work, provided the old stub builds with the
new framework
b) change the condition that recognizes LS (or FS) devices to always
true, so that EHCI gives up ownership if anything is connected (lines
484 and 312 in ehci_rh.c). I haven't tested this but it should work, and
effectively disable EHCI driver.
sorry it's taking so long.
I actually managed to find some time to work on HelenOS this week, but
blew it on even older project of getting gta02 qemu working (still no
success). Next time I'll prioritize USB
