Haven't heard of it. You might wanna drop buy www.drivers.com and look around if the company isn't in business. Also, check Windows Update and see if there's a driver for it.
Try the Windows NT drivers they might just work?! http://www.paperbits.com/drivers.asp?manu=LEO Image
sorry, I searched on the net for a while but could not come up with any XP drivers. So it seems there aren't any for XP! I would suggest getting another scanner from a company who has a large customer base.
