View Full Version : Cannot Locate XP Bluetooth Stack after Removing Toshiba's

03-26-2007, 01:17 PM
This is the problem I'm having:

1) I have a blackberry wireless device that can synch with bluetooth capable computers. However, it will ONLY be compatible with the embedded Microsoft Bluetooth stack in XP w/SP2.

2) The Laptop I am tryin to synch it with is a Sony, which ships with the XP stack disabled and a third party Toshiba Bluetooth stack enabled.

3) After this is removed as is required by the Blackberry, the Microsoft Bluetooth Stack still doesn't show up.

Okay, that's the fundamental basis of the problem. Now for some background info on what I've learned so far through much searching:

1) Microsoft will NOT offer technical support on how to reactivate their bluetooth stack for windows XP unless the OS was bought retail, but of course this was OEM, therefore I can't get their input.

2) Sony continually just defers me back to the Toshiba Bluetooth stack. After countless emails and calls trying to get them to understand I cannot use it, they still ramble off the same answers to me as if they are robots, and they will not give me information as to where or how to download the Microsoft Bluetooth Stack.

3) I have located the bth.inf and bth.PNF files that are related to the Microsoft Bluetooth stack in the C:/Windows/inf folder. However I'm not sure what--if anything--needs to be modified with those in order to reactivate the bluetooth stack.

4) When trying to use the run command "bthprops.cpl" nothing comes up, further showing that the bluetooth stack from xp is not enabled.

So, unless somebody has a more technically advanced solution, I fear my only options are to either remove SP2 and reinstall it thereby reinstalling the Bluetooth Stack embedded in the SP2 update, or buy a retail copy of Microsoft XP w/SP2 to install the utility separately. I've tried to find the uninstall package for SP2 before, and had no luck with the directions I found.

Does anybody know ANYWHERE I can just find a download for the bluetooth stack independantly? Any suggestions? Any help is appreciated.

# The Bluetooth Host Controller program is only available for Windows XP.
# To obtain the latest release of the Microsoft Bluetooth driver stack, go to http://download.microsoft.com/download/whistler/SP/1.1.1/WXP/EN-US/bt_stack_rtm.exe.

Thanks for the find. The only problem with that is I already have XP w/SP2 installed, so when I try to extract those files and then install them it says that they can only be installed on SP1 and that the files I have are already more recent.

Hey, Brandon. I'm having EXACTLY the same problem pairing my BB 8800 with my Toshiba Satellite laptop. I've been looking everywhere for some answers, but, like you, keep coming up dry. Tried the above .exe and got the same results as you. Good to know, at least, that I've got company. :)

Please post back (or e-mail me) if you find out anything, and I will do same.

Bruce, thanks for the reply. I've noticed this has given a number of people headaches from my searches, but because each person's situation is different by a few (seemingly insignificant) details, each solution has been tailored for those specific circumstances and, thus, I haven't had any luck with some of the other solutions I've seen posted.

I found that if you completely uninstall the toshiba bluetooth stack and then go into the "c:\windows\inf" folder and rename the "bth.inf" file to "bth.bak", and then restart the computer, the xp operating system will try and search for the drivers to install new hardware, presumably for windows' bluetooth stack. But when it searches for the drivers for the hardware named "ugx" and I select "allow windows to search for the drivers automatically" it always fails and tells me windows could not find the drivers.

For whatever reason, this solution of simply renaming the bth.inf file to bth.bak and restarting helped out another person who apparently had the same exact situation that I'm in, so I'm not sure what I'm doing wrong or what details he/she left out of their post. Let me know if you find anything or if you have any luck with this solution, and I'll stay on the grind for this answer as well.

I'm using VAIO notebooks for more than 4years (different models) and I can't remember if I could use my bluetooth just once without any problem.
I'm currently having the very same issue with my pocket pc (Touch Diamon) connecting to my notebook (SZ330p).

Trying to transfer files is not a big deal, but when it comes to using some applications, like phonepoint, you wish Toshiba never existed.

Anyway, I'm trying to uninstall the driver, but I've been stocked with installing the Microsoft stack.

I've windows XP Pro SP3, and I'm facing with the problem of finding UGX driver after uninstalling.

When I found this thread, I though my headache is ended, but no help as of yet....

I have had the same issue - and after much messing around resolved it by editing the bth.inf file (in c:\windows\inf).

First you will need to find out you adapter's Device ID: Open device manager and double click on the bluetooth device (probably a yellow quetion mark). In the box that appears, choose details. The string that appears gives the device ID for your adapter (my Belkin is USB\VID_050d&PID_0131).

Open the bth.inf file into notepad or similar and scroll down until you find "Device Section - Start". Find your adapter manufacturer under which there will be a list of device ids.

If your adater ID is not there, type in the details in the following format:

Belkin Bluetooth Adapter= BthUsb, USB\Vid_050d&Pid_0131

using your adapter's details to replace th Belkin ones above.

When you have done this, save the file and, in device manager, reinstall the driver. When asked for the various options select no to the internet and then "Install from specific location". Point the file location to c:\windows\inf.

This did the trick for me - my Blackberry can now connect to Desktop Manager without a problem.
