I just installed a new hard drive in my Latitude E642. I have installed drivers for all of the hardware in the machine but still have problems with three components listed in Device Manager. Braodcom USH, PCI Serial Port and an "Unknown device". There are no devices by these names in the Dell Downloads for the 6420. Can someone help me identify the drivers I need to download and install? Thanks!
Solved! Go to Solution.
DELL_CONTROLVAULT-WINDOWS-BI_A00_R308326 is the driver for broadcom USH
don't know PCI serial Port
So you need the Dell Data Protection collection and the ST MicroElectronics Free Fall Sensor . And for the Dell Data protection bit you need the driver pack and the middleware. If you still have the PCI serial port let me know

PCI Serial Port for the Dell Latitude E6420
Once installed it shows up as Intel Active Management Technology - SOL in the Device Manager.
