I have a 27" TB display working with a Macbook Pro Retina 15"
Keyboard and iPhone is connected to the TBD as LAN.
This works for half a day, then the keyboard is not working untilk I cut the TBD from the MBPR and connect it again.
So it is working for another 2-5 hours - then the same again.
it ***** because the full screen apps changes every times.
what can I do?

It's not clear to me what you mean when you write:
Keyboard and iPhone is connected to the TBD as LAN.
How exactly is the keyboard connected - surely not by a local area network?
I've had no problems with my Apple Extended USB keyboard - have you tried one of those?

It means that I have at the tb USB port a USB Keyboard and the iPhone plugged in
Additional a LAN cable is plugged in in the tb LAN

Some people have reported a problem with an Apple USB keyboard and the solution seems to be to use a USB extension cable between the USB port and the keyboard. I have no idea why this works, and I've never had any problems with the standard Apple Extended USB keyboard and its own cord.
Clinton
nope - I dont use the extension cable
the keybord is directly plugged in the TBD

You may want to try using an extension cable, as installing one seems to have solved the problem for some.
Personally, I don't have the problem and I've never needed an extension cable - but installing one has, as I wrote, worked for some. A cheap solution if it works!

Excellent suggestion on the USB extension cable!
Totally solved my problem with the apple extened keyboard.
Thanks.
Since the Thunderbolt Display has been released I have seen this issue on literally hundreds of display/laptop combinations. With and without the extension cable. I have not found any logic around the issue, trying different usb/thunderbolt ports, different sleep settings, power settings. This is a legitmate issue that should be addressed and Apple is not addressing it -- or can't address it. BTW-There is NO reason to engineer a product with an extension cable needed to operate the peripheral. The only way to solve this is to burn a USB port on your laptop. I am fairly certain the issue is power related over the Thunderbolt bus. However, I have also experienced issues with USB3 hubs on macs. So maybe it is a larger power issue.
Anyway, an Apple wired keyboard should just work out of the box.
TB Display loose keyboard at least twice a day
