I had this same problem and it baffled me but I found the solution. This worked for me. It appears as though the USB drivers got corrupted being placed on the dock the first time. I dont think I let the docking station finish installing the device drivers before I pulled it off... Anyway...

I had the same problem with a T500 docking station, when upgraded to Windows 7 , USB ports on the docking station were disabled. Used solution suggested by nerdherd and now all seems ok.

The discussion has apparently ended - yet the problem still persists, at least on the Thinkpad T400 with Advanced MiniDock 2504 I just bought second hand. I Installed all available updates (both MS for W7-SP1, 64bit, as well as Lenovo's), flashed the BIOS and everything.
Monitor, LAN and power passthrough (almost) work fine, though no USB support whatsoever. Tried your trick - in vain. Next to the USB issue, however, the docking station (DS) shows a few other issues: Pressing the DS *power* button won't do anything at all. Pressing the eject request button leads to the blinking state - and eventually falls back to stable lighting! Likewise, the FN+F9 combination won't initiate anything. Did the trick of "cold initialization" (= power off/shutdown) of both components I read about somewhere else, too.
Of course there's this dimension that it's a leasing/second hand model (both parts: notebook and DS) and I had to install almost all of the Lenovo/ThinkVantage stuff on my own following the W7 installation. And yet, as frequent as this problem apparently popped up in the past: Should this really be the reason for the malfunction?!? Apparently there's a known issue when it comes to the OS with lots of users reporting their first related problems only after upgrading to various W7 releases ...
Any news? Thank you!
