I guess I am doing something stupid. I've tried this on four different computers, three different cables, three different Teensy boards. The only commonality is me so I guess I am the idiot. I haven't even soldered the headers on yet so I know the boards are undamaged in any way.
I plug the Teensy 3.0 into any computer via USB and it blinks as advertised. I am using the right cable, the flat micro-B USB type cable. On most of the computers, when inserted the first time I get a driver installation failure which I guess is to be expected. I download and run Teensy Loader from http://www.pjrc.com/teensy/loader_vista.html for the three Windows 7 64 computers I have tried this on. It runs fine. I press the hardware button on the Teensy board and the Teensy stops blinking but nothing happens. In one case, at this point, the computer gave a success message for the USB driver:

But in all cases, the Teensy Loader has done nothing. It has not enabled any menu entries, changed text in verbose mode, changed the background image, or done anything else. I have tried this on an Windows XP SP3 32 bit machine as well with the Teensy XP loader at http://www.pjrc.com/teensy/loader_xp.html with the same results. I changed up the boards and the cables with the same results.
Oddly, despite the message saying the USB driver was successfully installed, Windows still thinks it is an unknown device:

Is this a problem by itself or expected? What am I doing wrong? Thank you for any advice.
