No, you will have to replace the parts.
I'm afraid it's true. As the USB 1.0 controllers are part of your motherboard there's only two options available to you:
- Replace the motherboard (and probably the CPU and RAM and maybe even the graphics card too - if you're using USB 1.0 it's probably pretty old)
- Buy a USB 2.0 PCI card (assuming that you have a PCI slot free)
