I recently revisited the driver installation on a Dell E6400 laptop. There was one stubborn driver that I couldn't get working, the "Broadcom USH" device. Dell's support website didn't list a driver for this so I went out on a wider search across the internet forum. I found a lot of posts talking about installing the Control Vault device drivers. So I grabbed the Dell ControlPoint Security Device Driver and found that it was useless. The drivers were wrapped in an installer (that I didn't want to run, I just wanted the drivers). Then I scrolled a little further down the page and found the Dell ControlVault Driver package (here's the page where I found it). After extracting that exe file I was left with a bunch of MST files and one MSI file. So I extracted the MSI and there they were, the elusive drivers. But it wasn't just a straight forward install.
I tried to install the driver, but it didn't work either. It told me it couldn't find one of the files. At first glance, everything was there. So I ran DPInst against it. It errored on two different drivers. I looked through their INF files and found that they were looking for 2 files that weren't there. A ccidflt.sys and a cvusbdrv.sys were missing. Looking in the folder there was a ccidflt.sys2 and a cvusbdrv.sys1. Close enough, right? I removed the extra number from the ends of the extension and ran DPInst again and it worked!
So there you go, sometimes drivers can be stubborn. But a little persistence pays off in the end.
