So here is the issue:

I downloaded and installed IOUSBFamily-315.4-log.dmg" for Mac OS X10.5.5 Build 9F33 to my MBP 2Ghz running 10.5.6 in preparation to jailbreak my iPhone 3G (2.2.1). After rebooting I get a panic kernel-power off and reboot message.

My hardrive only has about 5Gbs on it so I can't archive and install 10.5.x from the disk.

Any suggestions?

Thanks

First, try safe mode (press "shift" during startup)
Second, try popping the disk in, run permissions check
Third, using Target Disk Mode (hold "T" during startup), hook your computer to another mac using FW, backup your files, delete enough of the files to reinstall..

Thanks WikiNerd.
I hadn't tried target disk mode.

Disconnect all not necessary USB devices.

Remember you are using the kext from another build, so some devices will cause a kernel panic, for example, if you used USB kexts from 10.5.5 in 10.5.6, External USB drives and flash drives will cause a panic.

What to do?

Disconnect everything from the USB ports, just leave your keyboard connected and attach your mouse to your keyboard if possible.

Restart, and that should be it, just download & install 10.5.6 kexts from Apple Developer Connection.

Feel free to PM me if you got further questions.

Does your solution to plug an external USB keyboard work for Macbook Pro running OSX 10.5.6? I ran the script IOUSBFamily_kext_10.5.5 and it must not have completed properly as it disabled my keyboard and mouse. I tried Safe Mode but keyboard and mouse still inop. Need to get in to re-run the script to put kext 10.5.6 back. Any ideas? Was hoping that if I bought an external keyboard I would be able to log back into my Macbook Pro and reinstall kext 10.5.6. Please help!! Thanks!!!

I don't have a clue in terms of USB kexts, (I only have a basic understanding in firmware/driver operation). I would still go with the backup + archive/reinstall. Faster, easier.

Thanks for the quick reply! Just went to apple store to try the external keyboard, didn't work. They suggested the same thing you just did. Sorry to ask, but how do you do a backup+archive/reinstall? Is it through the DVD install disks and select "archive and install choice." Also, they mentioned this archive reinstall would not effect any of my existing programs or data that is already on my macbook pro. Is that true? As I have windows running on it as well through VM Fusion and other secure virtual drives that are not backed up through the normal time machine backup process. Appreciate any help you can provide. Thanks!!

1. Backup via the target disk mode ( mentioned above, you might like to look it up. )
2. reinstall via that "archive and install" choice

Thanks for your help! I was able to use a target disk to download 10.5.6 combo update and installed it from there. It brought back my keyboard and mouse! But have minor problem now with USB ports having an issue. Figuring out that problem now... thanks again!
