I see this tips doesn't works for everybody but just a few. I think it could be due to the chipset used in the hard drive enclosure.

If the solution no. 1 does not work, here is a more radical solution:

In a Mac of one of my clients I solved the problem reinstalling ONLY the following two 10.4.9 kernel kexts:


I did this using Pacifist on the 10.4.9 Combo Update Package (don't know if those kexts are present in the 10.4.9 standard update (aka delta) package).

This will give you the previous 10.4.9 USB functionalities.

Do this with Pacifist, not by hand! Otherwise be sure to fix the ownership of those files, or they won't be loaded on startup and you will loose keyboard and mouse. Anyway if you did it by hand, then fix them just doing so:

sudo chown -R root:wheel IOUSB*

Do this before restarting your Mac, or you will have to do this launching from Install CD and using Terminal (or via Terminal on another Mac, using ssh).

My problem is not exactly the same. I use a headset, and the mic isn't playing anymore. It's recognized in the input list, but nothing more.

I tried the 10.4.9 replacment but it was obviously for HD, can you tell me wich .kext I have to replace for my microphone to work again ? thanks

10.4.8 Kexts work for me, with an external USB drive with 2.5" 80Gb HD, and using pacifist from the original 10.4.8 Dvd. I have a Macbook C2d. Thank you all.
