Hello,

 

I tried installing XP SP3 on my Latitude D820 w/internal Dell Bluetooth 350 adapter last night. After installing SP3, everything seemed to be ok except that the Toshiba Bluetooth utility no longer recognized the adapter (when I tried to enable the radio, it said to use the switch / press fn+f2 to enable the radio, but it was already turned on). It appeared in device manager as an unknown USB device.

 

I called Dell support and over the course of 45 minutes, we uninstalled/reinstalled the driver. Setup completed ok (including running the utility that flashes the firmware), and the software installed. However, the last part of the setup process involves actually starting the bluetooth utility and it tries to connect to the adapter. This part got stuck and would do nothing but periodically display a message requesting I press Fn+F2 to enable the radio. If I press cancel, setup finishes, but every time I try to start the bluetooth utility, the same install program starts up and requests I press Fn+F2 to enable the radio. I can toggle the radio off/on and such (device manager reports it disappearing/reappering), but nothing actually makes it work.

 

We concluded that the problem is probably that SP3 introduced some problem, it was logged somewhere in the support system, and then we hung up. So I uninstalled SP3. The problem is still there and still acts exactly as described above. 

 

If I close out that install program, then turn the radio off then on, and then go into device manager, locate the unknown USB device (it says "USB Device" with a yellow question mark icon with a yellow "!" status) right-click and choose update driver, I can manually find the driver from the utility's install directory, making it show up at the top as a bluetooth radio and then the built-in windows software works ok (so far as I can tell). However, if I try to run the Toshiba bluetooth utility that came with the computer (I like it better), it uninstalls the driver (device manager makes it appear as an unknown USB device again) and then if I try to update the driver while the install program is running, any window that pops up about the driver is nearly instantly dismissed and/or hidden (presumably by the setup program).

 

Does anyone have any ideas of what I should try?
