Nevermind, I have found all the drivers.
Main Topics
Browse All TopicsI just bought a Dell Latitude E4300 and have installed Windows XP
Pro and Service Pack 2. I have downloaded the appropriate drivers from
Dell's support site and installed them. However, Device Manager still
shows two big yellow question mark items under Other devices which is
labeled Base System Device & Broadcom USH. What piece of hardware is this and which
drivers do I need to install?
Thanks for any help.

Xyden, you can find the driver for the broadcom ush from here
http://support.dell.com/su
Expand the applications tree, then download the control point security manager driver, this will take care of the broadcom ush unknown device.
Dell must have either updated or removed the driver from under the applications tree. On my system, there is nothing under the applications tree, and nothing called the ControlPoint Security Manager under any of the other trees either.
Here is the link I'm using...it's the same as Gage06's...

All - Have the same problem on the same model Dell. Installing the ControlPoint software 'found' the driver for the Broadcom unknown device but I still have one unknown device called "Base System Device." I've installed all of the drivers available on Dell's site for this particular unit. What driver needs to be installed yet?
Thanks all...
