Under No 3, there's a link for a driver that the developers of Route 66 thinks might work for USB GPS's. I have no idea if it works or not, I do know however that I bought a USB GPS from Ebay today based on the fact that the driver exists. I hope it does.
Otherwise check this out (translated by Google):

Please let us know your findings! I will try these once I get my GPS and get back to you.
Sincerely,
