This just started a few weeks ago, but I haven't really been home enough to try and fix anything.



When I plug in a USB thumbdrive, external HDD enclosure, nothing happens in OSX on my Mac Pro. Nothing shows up in disk utility, the desktop or anywhere else.

I've tried using 4 or 5 different thumbdrives, some FAT32, NTFS, HFS+ etc. Nothing shows up at all.

My mouse and keyboard function just fine, so I know the ports themselves are doing something. but that seems to be the only thing that works.



Any ideas? I can't find anything using google that gives me any idea where to start.

The drive might be damaged and can't mount.

There are plenty of postings on this on the Apple forums...
Apparently this has started with 10.5.3. If you roll-back to 10.5.2, you will be able to use these drives again.

There doesn't seem to be a common factor with which drives will or will not work, but the common factor is that they are all listed if you go into System Profiler.
