Latitude E5400 - Unknown devices listed in Device Manager
Hey guys,
We just got a shipment of new Latitude E5400's here. I started working on one, reformatted and installed a clean fresh copy of WinXP (SP2). I followed up by installing the device drivers in the correct order as recommended by Dell.
However, I have a list of unknown devices listed in the Device Manager. They are as follows:
Audio Device on High Definition Audio Bus
Base System Device
Fingerprint Sensor
Modem Device on High Definition Audio Bus
SM Bus Controller
The Audio Drivers have already been installed, despite the listing above...
I have a feeling it has to do with the Chipset drivers, or perhaps some drivers are not listed for this machine on support.dell.com?
Please advise.
Regards

What was your resolution for the "Audio Device on High Definition Audio Bus"? I've been talking with customer support and researching for hours with no success.

I too have an issue with these unknown devices:
So none of my USB ports are working, despite having all the drivers installed.
The speakers work but I assume the unknown device is the microphone.
Any ideas?
