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.

"Unable to open connection to server" error when connecting to Exchange on Android 2.2

There seems to be a problem when using the default Android Email application to connect to an Exchange Server 2010 SP1.

When you go through the setup procedure and enter all necessary info to setup a new account on the phone, the setup will eventually fail throwing a "Setup could not finish" "Unable to open connection to server." message.

On the server side, the following log is generated:
 RequestBody :   
 <?xml version="1.0" encoding="utf-8" ?>  
 <FolderSync xmlns="FolderHierarchy:">  
 AccessState :   
 AccessStateReason :   
 ResponseHeader :   
 HTTP/1.1 449 Retry after sending a PROVISION command  
 MS-Server-ActiveSync: 14.1  

Google is aware of this ( and they calim to have fixed it but it is unknown when an update will be pushed.

The interesting thing though is that the Email application which is included with the 2.2 emulator seems to be working fine. So what we will do is extract the Email.apk from the emulator and install it on the phone.

Requirements: Rooted device, installed ADB and Android 2.2 Emulator.
Note: This will remove any improvements a ROM developer has included in Email.apk.
Disclaimer: I am not responsible if by doing this you damage your phone/data/life in an way. Backup your data first, preferably by making a Nandroid backup.

Autostart script changes for Calibre 0.7.27

In version 0.7.27 of calibre, the "auto reload" command has been unbundled from "--develop". As a result, the script in the previous post has to be updated. Only the script changes, the rest of the procedure is the same.

The "DEMON_ARGS" line changes from
  DAEMON_ARGS="--develop --with-library=$CONTENT --pidfile=$PIDFILE --port=$PORT --max-cover=$MAX_COVER --daemonize"   
 DAEMON_ARGS="--auto-reload --with-library=$CONTENT --pidfile=$PIDFILE --port=$PORT --max-cover=$MAX_COVER --daemonize" 

The full updated script can be found after the break:

Downloading and Parsing the IEEE MAC address OUI to a CSV in VB.Net

The following function will parse a OUI file and create a CSV file where each line will contain the first six characters of MAC address and the company they are registered to. To see how a OUI file looks like click here (it is a couple megabytes long).A function to download the OUI (or any file via HTTP) is also provided after the break.

It takes two parameters: "FileInPath" is the location of the OUI file and "FileOutPath" is the path of the CSVyou want to save to. If no file is there, one will be created automatically.
