I beleive that you had downgraded and installed a retail version of XP by erasing the preinstalled version of Vista in your Notebook.
However, all the drivers required for your Notebook may not be available with HP if your Notebook is preinstalled with Windows Vista.
I recommend you to try downloading and installing the drivers for HP Quick Launch Buttons from the link below for the first Unknown device in the Device Manager :
ftp://ftp.hp.com/pub/softpaq/sp38001-38500/sp38266.exe

Save the file on to the Desktop or My Documents folder and double click once the download is completed to install the drivers.
For the Ethernet Controller, I recommend you to download the LAN Card Drivers from the link below :
ftp://210.51.181.211/cn/nic/INSTALL_VISTA_6208_0922.zip

Coming to IEEE 1394 controller, you need to download and install the Chipset Drivers which are available through the link below :
http://us.download.nvidia.com/Windows/nForce/15.24/15.24_nforce_winxp32_international_whql.exe

Make sure that you download and save the files in the Notebook and double click them once the download is completed and restart the Notebook after installing each of the drivers provided above.
Hope this helps...

Unknown device win 7


Usually, when you buy any hardware the drivers come along with it on a disc. If you lose the driver disc you can always download the necessary drivers from the manufacturer's website. But what do you do when you are not sure of the manufacturer of the hardware? Well now you will know what to do.

Open Device Manager (Control Panel>System>Hardware>Device Manager) The hardware whose drivers are missing will appear as Unknown device, so it's easier to locate the device. Right click on the unknown device and click on Properties. Under the Properties window click on Details tab and select Device Instance Id from the drop down box. You should see a code similar to this: PCI\VEN_8086&DEV_27DC&SUBSYS_30868086
& REV_01\4&1E46F438&0&40F0 In the text above the Vendor ID and Device ID will always be in the same place for the driver Vendor ID = 8086 and Device ID = 27DC your numbers will be different. Once you have obtained both the IDs, proceed to PCI Database. There you can either search for the vendor from the vendor ID or directly get information about the device along with the vendor name by searching with the device ID. http://www.pcidatabase.com/
b>Windows 7 First, please disconnect all USB devices and then perform the following steps:

Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.

In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".

Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".


Then, restart your computer and Windows 7 will reinstall all USB controllers automatically. Hope this helps. b>

I would manually un-install, and then reboot so the system could re-install. Also do a complete system virus scan, just to be sure
that a bug isn't operating.

You should first check device manager for any issues with Network drivers.

Start--> Run --> devmgmt.msc

This command will launch "Device manager" window.

If you see a Yellow exclamation mark in device manager for NIC, follow the following steps to identify the card that is installed on your computer.

  1. Open Device Manager (Right-click My Computer>Properties>Hardware>Device Manager)
  2. The hardware whose drivers are missing will appear as Unknown device, so it’s easier to locate the device.
  3. Right click on the unknown device and click on Properties.
  4. Under the Properties window click on Details tab and select Device Instance Id from the drop down box.
  5. You should see a code similar to this
    PCI\VEN_8086&DEV_27DC&SUBSYS_30868086&REV_01\4&1E46F438&0&40F0
  6. The portion of the code highlighted in RED is the Vendor ID and the portion highlighted in GREEN is the Device ID. In this example:
    Vendor ID = 8086
    Device ID = 27DC
  7. Once you have obtained both the IDs, proceed to www.pcidatabase.com . There you can either search for the vendor from the vendor ID or directly get information about the device along with the vendor name by searching with the device ID.
After you find out the information about the device and the manufacturer of the device, you can visit the manufacturer’s website and download the corresponding device drivers.

I also upgraded a new Compaq C751NR from Vista to XP, and the last yellow tag in device manager was-acpiHPQ0006

I used the driver from ftp://ftp.hp.com/pub/softpaq/sp38001-38500/sp38171.exe

and used the 'setup.exe' in the folder. Worked perfectly.

Networking Problem


By local network do you mean using a wired connection or a wireless connection? I gather you mean with a wire.

The following link is to a PDF page listing the lan drivers from acer for an Aspire 3680 --

Drivers Link

The second and third entries on the list both appear to be wireless adapter drivers for built-in hardware (atheros or broadcom). Are you sure the driver you have loaded is the correct driver?

To determine which if the two may be suitable for your machine try the following

Click Start and right mouse click My Computer and select properties

Select the general tab and click on device manager

find your wireless adapter probably preceded by a yellow question mark (?)

double click on the wireless adapter entry

get the name at the top of the general tab and
the click the details tab and record the
device instance id value

Report what you found back here in a comment.

Hopefully the name will contain atheros or broadcom of not I hope I can lookup the device instance id string to determine the manufacturer of the wireless adapter.
