USB connectivity for old laptops?

Does anyone know of a product or a way to add USB connectivity to an older laptop – IBM ThinkPad 560E? It has 16-bit, type II PCMCIA ports, the latest BIOS that IBM released, and it’s running Windows 98.

I know there are USB PCMCIA Cardbus products out there, but these are obviously not compatible.

Any info or suggestions would be greatly appreciated.
