HTC Desire Z (AKA HTC Vision AKA T-Mobile G2) and ADB drivers

I just got myself a Desire Z and once again the ADB drivers fail to install in windows.

It is the same problem described and solved in this post.

To fix:
1. Make sure you have updated the SDK and the USB driver to the latest version.
2. Open the android_winusb.inf file (located under the android-sdk-windows\usb_driver directory) using a text editor. I personally prefer Notepad++.
3. Add the following lines under the [Google.NTx86] and [Google.NTamd64] sections:

 ;Desire Z  
 %SingleAdbInterface%    = USB_Install, USB\VID_0BB4&PID_0C91  
 %CompositeAdbInterface% = USB_Install, USB\VID_0BB4&PID_0C91&MI_01  
 ;  

4. Save the file
5. Try to install the driver again.

If it still fails to load, follow the instructions from this post to find the correct VID and PID of your phone.
