I was using win2k and loving it until the KB port on my mobo went Tango Uniform. Anyway, I bought a USB KB and pluged it in...Win2k crashed repeatedly-telling me that "IRQ is not less than or equal to......."
I diagnosed it to be a conflict between the keyboard and my scanner. When one if plugged in, fine. When they both are, not fine.
They seem to work fine in win98.
