Compaq Evo N400C

[pritska]

I have rebuilt one of these with Windows XP. All drivers are loaded fine, except one which is a USB Device.
The computer sits on a docking station of sorts. In device manager, the item is listed with the yellow exclamation mark. USB device on Location 0.
I have trawled HP/Compaq site but cannot find what this driver could be, so I can install the correct file for it.
I was just wondering if someone out there has a similar computer and managed to demistify this strange USB device.

Howdy:

Is USB enabled in BIOS ??

I have done both of the above, installed the softpaq from compaq site, and USB is definately enabled in BIOS. I have taken the laptop off the docking station, but the exclamation mark is still there, so it's something to do with the laptop itself.
There is some Wireless LAN stuff that is supposedly an option on this machine. I am pretty sure that this option is NOT installed on this particular machine.

What is connected to the system via USB??

nothing. two usb ports on the actual laptop, one on either side of the machine. two on the docking station. not that it matters, as the device is on the laptop, not the docking station.

Hi!
Can you check the device manager
You should have :
Some or one PCI to USB host controller
Some ore one USB host controller
Some USB root HUB

All you need to do is go to the WindowsUpdate site and install the USB drivers for it. I've done this many times... rebuilt many Evo's.

Good luck
