My issue is very similar as well. Sometimes on startup (with the thunderbolt display and macbook pro already connected via thunderbolt cable) my cursor will be frozen in the upper left hand corner of the screen. While frozen, no connected devices (trackpad, wired keyboard, etc.) are recognized.
When I restart with the thunderbolt display disconnected my macbook pro will normally boot correctly and not freeze, then I plug my thunderbolt display in and it will work. This is an extremely annoying issue for expensive devices that are advertised to work seamlessly.
Apple needs to address this issue with a driver/software update.

Unfortunately, the problem reappeared after the first shutdown. Now I have no Ethenert nor USB nor sound again
Currently, Apple support is considering this issue as an hardware problem. This may explain why it arise randomly and in very different contexts.
For me the next step is having both display's mother board and power board replaced...

Same problem here. New TB display and MBP. Display is dead half the time after Software update 10.7.3.
Only solution that works for me is. Unplug power when you leave the office. Next morning it's fine - and stays on as long as you set Energy option to Never sleep on Power adapter, but you must power down overnight to let it re-set. Suspect software version / firmware compatibility issue. Hope updates will fix that.

I have had similar issues with my TB display where I have to shutdown my MBP and then restart. At night I cannot just eject my TM drive and put my laptop to sleep, I have to fully shutdown and restart when I get home. This is completely unacceptable from Apple selling premium products. I think this is related to other USB issues Apple is having. I had a backup drive failed and bought 2 new USB drives, both were USB 3 and would not be seen. I had to switch to a FW drive. This is the case for 10.7.2 or 10.7.3. So like ejkitchen, I believe this is software or firmware.

For the past 3 days I have had no issues after trying something different. After reading btully's post, what I decided to do is power off the Thunderbolt display every morning before I plug my laptop in and so far this seems to work. 3 days is not a data point but perhaps if others try too for a bit, we can see if this solves the issue for some of us. I will keep you all posted and see if this continues to work.
One thing to note as well, is that if I power off the Thunderbolt display while logged in and do not retract the plug first, the system hangs often. I am not sure if I am imagining this as I think once you power off the display it must be just like pulling the cable out no??
Anyways, one thing is clear, there is a problem somewhere with either Thunderbolt display firmware or Mac OS X drivers.

Quick update. So all week I unplugged my monitor every single time before plugging it into my laptop and the problem has not occurred. I will wait two more weeks and after that, if it still works, I am pretty sure this is a monitor firmware issue.

As decided by Apple support, both mother board and power board where replaced on my Thunderbolt Display...
and the problem is still not solved!
Rebooting, resetting SVC and PRAM has no effect: I still have no Ethernet connexion nor sound nor USB port working on the Thunderbolt Display.
Curiously, when my MacBook Pro connected to the Thunderbol Display is turned off, my iPad plugged to an USB port on the Thunderbolt Display will charge and stops charging as soon as the MacBook Pro is turned on!?
I now hope that it is really a firmware issue and that a fix will be available soon.

Well, power down over night worked for about a week for me. I gave the screen back to Apple this morning. They will replace as soon as they have stock. They seem to think it's faulty. Will keep posting.

Add me to the list. I tried everything posted here today, and no matter what I do the USB ports on my TB display do not work. I even updated to 10.7.4 this morning, and nothing. Display firewire and ethernet work fine, just no USB at all.

I had to perform an SMC reset to get the MBP to recognize the Thunderbolt. Recognizing the display USB ports is very inconsistent and I am not going to perform and SMC reset everyday. I'm calling Apple today to either get this display swaped or repaired.
