I am running Win 7 Ult 64bit and the only USB driver that did not install correctly was the ADB device. It comes up labeled "Android Eclair". I downloaded the USB drivers package from Augen and unzipped the package to my desktop. To get the driver to load I had to modify the android_winusb.inf file. I have attached that file to this post. Detach and change the file from a txt file to an inf file, then replace the file in the 64bit driver package package and point the driver install to it.The driver loads and is working for me. I was able to do the market update making the ADB connection with no issues.
