Hi Perry,
Thank you for responding!
I found the answer last night. The update installs a bad
IOUSBFamily.kext and bad
IOUSBMassStorageClass.kext into the system.
The solution is to copy those files from the original DVD to the corresponding location on the harddrive: from (DVD)/ System/ Library/ Extensions/ * to (HD)
/ System/ Library/ Extensions/ *This solution came from an old 2011 post on sysprobs . com, from a commenter named Semi, to give credit where it's due.
Thanks, and I hope this helps someone else in the future.
