I do not know what the device is that you're describing..... eg: mouse, keyboard, other? We provide a Comment Box in our request form for a purpose... it's not just there as a web decoration.
If this is a keyboard, it only needs a driver to enable the special internet/multimedia related keys (if present). The regular keys do not require a driver since the OS will provide support for the device automatically.
Here is a link to an article that has some good troubleshooting steps for wireless keyboards, including how to re-synchronize it with the computer.
The Microsoft wireless keyboard or mouse does not respond as expected or responds intermittently
And here is a link to a driver that you can try: http://www.microsoft.com/hardware/en...-keyboard-1000
As a last resort, open Device Manager, find and double-click the hardware device you need a driver for, click the Details tab, select "hardware id" and give me the hardware id string that begins with "PCI\VEN" or "USB\VID" (depending on the interface), (1st./top line of text only). If no driver has been installed, the device may be listed under "Other Devices".
