How to fix USB error "unknown device"?

Question

When I am plugging the USB-to-Parallel BF-1284 in a USB port, “unknown device” is displayed and I can not use my parallel printer.

I have a Dell Dimension 3100 Desktop with windows XP Home edition SP3. I have installed all updates for XP.

I have tried on a Dell Latitude D820 Laptop and everything is working fine.

You need to install the correct drivers for your USB-to-Parallel adapter.  Do a search on the exact model name and see if you can find a site to download the drivers from.
