This is what i keep getting
USBF: 16.991 EHCI controller unable to take control from BIOS
USBF: 16.991 AppleUSBEHCI[0x2c56000]: unable to obtain ownership: 0xe00002be
USBF: 16.991 AppleUSBEHCI[0x2c56000]::UIMInitialize - Error occurred (0xe00002be)
USBF: 16.993 AppleUSBEHCI[0x2c56000]: UIMFinalize 0 0 0x2c98700
USBF: 16.993 AppleUSBEHCI: unable to initialize UIM
I am running 10.4.8 and i ran your instructions 100% to the tee.
Any help would be greatly appreciated
BTW i have a Intel D915GUX motherboard and i know most new motherboards has the option to hand off EHCI in the bios , mine does not have that option as it is older and i do have Legacy USB enabled or else my USB keyboard does not work in the bootloader screen.
Not sure if this has anything to do with it but this is what i see in my USB section of the system profiler

And the system run's fast still. No change in speed when it's disabled. One thing that i did notice as well is the following. I have a seperate card that is usb 2.0 and i believe on the intel board the ports can be both 1.1 or 2.0 (depending if it is enabled in the bios or not).
this is what shows up

Didn't have this one before (only when USB legacy is disabled)
