I work on many machines.

Here is what I did and it worked for me:

I have a Windows 7, 64 bit machine with an unknown driver ACPI\FnBT0000. I downloaded the file

It is available for download from here:
GIGABYTE I SERIES I1320 ? Descargar drivers @

Once it downloaded, I unzipped the zip file (using 7 zip) and navigated to the folder:

In the above folder, there is a file called "virkbd.inf". That is the driver for this.


Manually install the above "virkbd.inf" driver file as follows:

Start Button -> Control Panel -> Hardware and Sound -> Device Manager -> right click on the unknown device -> Update Driver Software -> Browse My Computer for Driver Software -> Let me pick from a list of drivers on my computer -> Have Disk button -> Browse button -> find the "virkbd.inf" file and follow the prompts.

When you are done you should see "Virtual Keyboard Device" as a new, working device under "System Devices" category listed in Device Manager.
