Try again with a keyboard and mouse that are known to work otherwise.


Here's an Apple Support document with some keyboard troubleshooting tips.

Maybe there's some help there.

If your Firewire or USB isn't recognizing any device.  A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:

1. Shut the machine down.

2. UNPLUG the power lead to the computer and any firewire/USB drive or devices.

3. leave it for 10 minutes.

4. Connect back up and reboot.
