Missing Vista Device Driver D430

This question is not answered
Device.jpg

The device  manager (see attached) shows a missing device driver on my dell d430 using windows vista - bluetooth works, so I don't think the missing device driver is bluetooth.

I believe the missing driver might be for the broadcom tpm, but I downloaded the R170381 driver and installed it without seeing any change or any tpm device added.

Any ideas what this might be?

  • In case it's useful to identify the devices, the hardware IDs for the three devices are:

    BTHENUM\{00000000-deca-fade-deca-deafdecacafe]_VID&000205ac_PID&1294 - BTHENUM\{00000000-deca-fade-deca-deafdecacafe]_LOCALMFG&000a

    BTHENUM\{8e777301-0000-1000-8000-00805f9b34fb}_LOCALMFG&000a

    BTHENUM\{a2157972-3541-4d0b-a551-b3abe639f526}_LOCALMFG&000a

  • By looking at a e4300 running windows 7, it looks like two of the missing drivers (number 2 and 3 on the list above) on my d430 running vista are "bluetooth pan" and "bluetooth rfcomm".

    Google shows a fix for this problem for winxp, to force windows to install the missing bluetooth pan and rfcomm drivers from the microsoft bluetooth stack, but this fix will not work with vista.

    Any ideas? There is no mention of this problem in dell support

  • By chance, I installed vista sp2 and two of the three missing drivers were installed during the upgrade process - I now have:

    Bluetooth Device (Personal Area Network)
    Bluetooth Device (RFCOMM Protocol TDI)

    ..and the only missing driver is

    BTHENUM\{00000000-deca-fade-deca-deafdecacafe}_VID&000205ac_PID&1294
    BTHENUM\{00000000-deca-fade-deca-deafdecacafe}_LOCALMFG&000a

    I'm guessing this a bluetooth audio driver/A2DP

     

    Any ideas on how to get this driver installed?
