Apologies - have re-posted with the formatting corrected.
Hi all,
There appears to be a Badly signed driver file within the Bluetooth Device-Driver install-package that is available on the 'Downloads' section of Sony Customer-support web-page for Sony VAIO VPCJ23S1E/B PC.
PC : Sony VAIO VPCJ23S1E/B
OS : Windows 7 HomePremium 64-bit with Service-Pack 1
Hardware : unmodified from original purchase
The PC contains the factory-fitted Bluetooth unit (an Atheros AR3012 Bluetooth adapter) :
Hardware ID: USB\VID_0489&PID_E036&REV_0001
1. Location of Driver install file:
-----------------------------------
The device-driver file contained within the Driver Pack available at URL :
http://download.sony-europe.com/PUB/VAIO/Original/BRDBLT-00248052-0042.zip?conditionsbox=on
and found from the Support web-site :
http://www.sony.co.uk/support/en/product/VPCJ23S1E_B/downloads/BRDBLT_00248052_0042_5814
2. Details:
-----------
This device-driver install-package includes the device-driver file : 'btwampfl.sys'
Windows is reporting that the digital signature of this Bluetooth Device-Driver file "btwampfl.sys"
has been revoked by its issuer.
Signer information:
Name: Broadcom Corporation
Signing time: 16 March 2011 01:59:24
Certificate information:
Issued to: Broadcom Corporation
Issued by: VeriSign Class 3 Code Signing 2004 CA
Valid from: 27/02/2009 to 20/04/2012
The "Device-Status" of the Bluetooth device shows :
"Windows has stopped this device because it has reported problems. (Code 43)"
Looking at the 'Driver Details' after the package is installed :
C:\Windows\system32\DRIVERS\btwampfl.sys
is marked as not signed.
Looking at the 'Digital Signatures' tab within the Properties dialog of
C:\Windows\system32\DRIVERS\btwampfl.sys
shows the Digital Signature issued by Broadcom has been revoked
and the following message is shown :
"A certificate was explicitly revoked by its issuer."
Any thoughts on remedying this ?
Cheers,
Steven
