Dell Latitude D820 + Dell Truemobile Wireless 300 Bluetooth Module = No Happiness

When I purchased my Dell Latitude D820, I purchased an internal Dell TrueMobile 300 Bluetooth Module.  I wanted to be able to make use of the Bluetooth technology to connect my cellphone.

My cellphone is a Motorola e815, and it has integrated Bluetooth.  It is possible to make use of this to enable file synchronization and contact management on the phone.  Even though I have a USB cable, I wanted to make use of the wireless connectivity.  For some reason that I cannot recall, the Bluetooth module refuses to work under Windows XP.  It did initially work, as I was playing with the phone late last summer, but I had some problems getting it to connect to my PC.  Essentially, the two would connect, but the phone did not like the passcode I was providing from the laptop.

Additionally, I know the module is not the problem, as it works under the Windows Vista installation I have on my laptop.  My laptop is capable of dual-booting, and I have a partition running Windows XP and one that runs Windows Vista.   The module works as it should.  Essentially, any of the drivers I have looked at complain about not seeing a Bluetooth device to install a driver for.  If they are installed, though, it complains about a need to turn the radio on, which is clearly the case.  Additionally, the driver asks me to press “Fn + F2,” which is unnecessary given that my laptop has the switch on the left of the laptop.  For some reason, Windows refuses to see the device.

On Sunday, I decided to take a crack at seeing how I could resolve this problem.  Nothing I found would resolve the problem.  Reinstalling the driver from Dell is not an easy task, as Dell only shows the TrueMobile 350 Bluetooth module, which my laptop does not have.  I tried just about every solution I could find, but nothing seemed to work.  I even tried a repair installation of Windows XP just to see if I could possibly return the machine to a known state and begin the problem resolution from there.  Nothing seemed to work.  The icon continues to sit in my system tray, taunting me with an inability to see the module.

The one thing I noticed is that module is seen as a Human Interface Device in Device Manager.  According to all other documentation I can found, the device should show up as a Bluetooth Device in Device Manager.  I know the device is working in the BIOS as well, so the problem is exclusively a Windows driver issue.

I really do not relish the notion of flattening my laptop install.  If I have to go exclusively Vista, I may make that leap just to accomodate my Bluetooth desires.   I have yet to see anything online or in the Dell Community Forum that helps me fix this problem.

    Marius:
    After I had it working in Vista, it decided to “appear” in my XP install. I need to dabble with it a bit more, but it was detected when I used it just fine under Vista. Moreover, it appears as a Dell Wireless 350 Bluetooth Module under Vista, which is interesting. All I know is it works as it should. I was able to sync my phone via bluetooth last week, and I can move files to it, too.

    I am going to test the link you sent me in short order, though.
