You may be better of with a simple USB logic analyser. As a serial signal is a 
bit too transient for an (old) scope.

I find the http://www.saleae.com/logic/ one to work splendidly for things like 
that.

Though in your case something like a bus pirate 
(http://www.sparkfun.com/categories/177)  or that logic sniffer further down 
the page may already be enough.
