Okay i did a update to 10.5.5 and now i reboot and get this error and it hangs in the boot process. cpu lite is on the whole time but nothing happens. max time left on 10min.

error "failed to load extension com.apple.driver.apple.usbehci"

i only assume this is a error b/c of the word failed and the fact that the text is in yellow.

Any ideas would be great. for those of you that have helped thank you for your patients with this newbie. But i AM LEARNING...SLOWLY
