Looking in the Device Manager for a DELL E6500 running Windows 7 Professional displayed the Broadcom USH item underneath the node for Other Devices noting that there was a problem with the device. Now previously simply trying to update the driver software by instructing Windows to search online was unsuccessful, with Windows notifying me that it was unsuccessful to install the Broadcom USH as the driver software was not found.
But going to notebookreview site at http://forum.notebookreview.com/dell-latitude-vostro-precision/298801-e6400-e6500-best-drivers-apps-tidbits-3.html one commentator noted that the Broadcom USH is the Dell Control Point Security driver for the DELL E6500, which even though you may not have it installed still requires the software.
I went to http://www.dell.com and then navigated to the Drivers & Downloads for Latitude E6500 section. When you search for the driver and you are presented with filters, use the ControlPoint item in the Category filter.
I found the required driver pack at http://support.dell.com/support/downloads/driverslist.aspx?os=W732&catid=60&dateid=-1&impid=-1&osl=EN&typeid=DRVR&formatid=-1&servicetag=&SystemID=LAT_E6500&hidos=W732&hidlang=en&TabIndex=&scanSupported=True&scanConsent=False
The download itself places a 75MB file Dell_ControlPoint-Security-D_A18_R269802.exe executable on your hard disk. This executable places the required drivers onto your system and will require a restart after installation. As soon as your system restarts Windows will update and notify you to NOT shutdown the machine during this process. After installation a new ControlVault Device node will be listed in the Device Manager and the troublesome Broadcom USH item will not be listed anymore.
