I updated my mid-2010 Mac Pro to update 10.7.3 this morning. Since then, I have had three occasions today, each one worse than the previous, where all USB devices connected just locked up completely and were totally unresponsive.

This includes my keyboard, mouse, and video camera.  Those are the only devices that are connected to this computer.


One at a time I have tried disconnecting and reconnecting each device with no success.  Interestingly on a couple of occasions, my keyboard would stop working but the mouse daisy chained out of the keyboard worked without any issues.


The most recent incident absolutely everything locked up and the only option I had was to do a hard reset of the computer.  When I logged back in I quickly enabled the Bluetooth support and grabbed my wireless keyboard and mouse so that I can work.


Has anyone else encountered this yet?  I know there aren't that many Mac Pro users any more.


In the meantime, Time Machine is performing a full backup and I think I will downgrade back to 10.7.2.


I wish I could go back to 10.6.8 but since this Mac Pro shipped with 10.7.2, it will not accept an earlier version of OS X.  :-(

Mac Pro, Mac OS X (10.7.2), Mac OS X 10.7.3

    Same problem here: after update I encounter several strange USB behaviours with keyboard, mouse and internet. Thanks god a simple disconnect and connect of the USB device (a hub with 7 connections, 5 of which are used) resolve the problem temporarily - until OSX 10.7.3 again decides to make troubles...


    Quite annoying...

    I have a MacBook Pro mid-2010 with 10.7.3, but the only USB devices that I've plugged in was my external USB drive and I haven't had any issue with that device.

    Well, it seems that reinstalling the update (not via "Software update"m but via the download) helps, at least it seems to have done so in my case...

    Same issues here, tried reapply combo patch too.

    Please either log a bug if you are registered as developer or use the feedback option on lion to report this to apple otherwise nothing will be done about this.

    Wow, Same issue here on my Early 2008 Mac Pro. After 10.7.3 update, my USB ports have been behaving erratically. The problem actually seems to be getting progressively worse too.


    From what Ive gathered so fat, it seems almost as if the ports are now underpowered. Plugging a keyboard directly into the USB port seems to work indefinitely. As soon as I add other devices to same port, the new device won't work.


    My first assumption was that my USB hub was shot, but then I tried the ports on the back of my Cinema Display and they were all jacked up too.


    I tried plugging another keyboard directly into the front USB port but That didn't work either, as it seems there was no power for it due to the other devices plugged into the back. I unplugged everything but the front keyboard and it still didn't work until I restarted it.


    Extremely hard to troubleshoot how this issue is behaving. Like I said, erratic is probably best description.


    This is the worst bug I've personally experienced after an update to an OS since I've been using Macs on System 7.


    I really hope Apple fixes this ASAP.

    I should add that I just booted I to Windows 7 using my BootCamp partition and the USB issue exists there too, which leads me to believe that this is not an OS issue.  Hate to be the alarmist here, but is it possible the update permanently fried something on the logic board?


    Also I should add that this just happened to me today after installing the 10.7.3 "supplemental update"


    Why was this not labeled as an incremental update? It still says I'm running 10.7.3.

    Apple is the new Microsoft with Steve J gone. 10.7.3 update is a real piece of sh1t. With this update, I cannot use my USB flash drive. On the exact same machine, if I use VMWare fusion, I can read and write from Windows. Just not from Finder. ******* stupid update. Cannot mount a USB flash drive on the mother OS, although it works fine in the Windows guest OS.


    Just junk. I am not going to update my Mac anymore. The QA team at Apple should be fire!!!
