    Here's the issue I am having.
    I can plug in an external USB keyboard and mouse however I can not mount and USB flash drives or USB external disks.

    I get the following error message:

    kernel Flash Disk : family specific matching fails

    I am running OSX 10.5.8 on a 15" Macbook Pro 2.53 Ghz

    Any suggestions? Apple Care has not be very helpful so far.

    I've verified/repaired disk permissions with lo luck.

    are there any software updates you can do?

    a quick google doesnt reveal any "quick fixes" :(

    the problem definitely seems software related.
