Yeah, I've run into this a lot with printers too.  Ironically it's the 
high-end stuff that tend to be the worst offenders when it comes to the 
USB iSerial descriptor.

(think photo kiosks that may have multiple indentical printers plugged 
 in, but each has different media loaded -- you need to be able to 
 identify each one reliably..)
