No, OHCI should be the correct driver for the chip in your laptop.
I suspect that if you do a little more testing, you'll find out
that by disabling OHCI, you don't have any USB ports that work.
If you're wondering how your internal keyboard/trackpad still
work, that's because they aren't USB devices. Apple still uses
ADB for these on all their laptops as far as I can tell.
