Change Bluetoth stack for MSI wind U100

The first thing you need to do is remove the Toshiba bluetooth- go to Add/Remove Programs and remove it.Then do a reboot and Windows will pop up a couple of detected new hardware dialogs - just cancel them though, they won't find drivers even if you do a search online.What you need to do is go to device manager and take a look at the properties of the unknown USB device with the exclamation mark.

This will be the Bluetooth module. In the properties window go over to the Details tab and take a look at the Device Instance ID. Here you will find the VID & PID for the bluetooth module. I assume they will be the same on all Wind's/Advents etc.. as long as they use the same bluetooth module in them all. Now go and edit c:\windows\inf\bth.inf (make a backup first if you want).

Now, you could put a new manufacturer in here or just go straight down to the section: [Toshiba.NT.5.1]. Then copy and paste the whole 'TOSHIBA Intergrated Bluetooth 3=' line, so that there will be two lines exactly the same. Then change the new duplicate line from Bluetooth 3= to Bluetooth 4=. Also change the current VID & PID on the new Bluetooth 4= line to match up with the ones you got from the device manager. So final line looks like this:

TOSHIBA Integrated Bluetooth 4= BthUsb, USB\VID_0DB0&PID_A97A

Then, save the file and do a scan for hardware changes in device manager (right click on your computer name). All being well, it should now detect your bluetooth module as a 'TOSHIBA Integrated Bluetooth 4' and install a whole bunch of drivers for it.
