I just went through a similar experience. In my case, I was using a computer that had reliably attached to several different Nexus One's previously, but two different Droids failed to be seen by ADB -- even though the devices enumerated properly (showed up in the device manager as Android devices) and even though the N1's were still able to be seen. I got past this by attaching a Droid, using the windows device manager to delete (not just uninstall, that didn't work) the driver, then the device moved to the "unknown devices" category. From there I told windows to install the driver; I pointed it at the same usb_driver directory that was previously installed, and things worked after that. No difference in the driver that I can see, but clearly something was different since it works now (and still works for N1).
