If it happens to need USB 2.0, then you will need to buy some hardware. To my knowledge, it's impossible to make USB 1.0 work as fast as 2.0 simply due to software changes and the like.

If it's a desktop we are speaking of, you can find a PCI card that has USB 2.0 ports (Cost varies with how many ports and perks you get with the card, but the price range seems to range from $18.00 - 32.00). There are also methods of making front-mounted ones ones; and this article walks you through such a process.
