About two years ago I was working on getting USB Host mode working  
"out of the box" on the GP2X, and I ran into this problem - the  
missing cap/resistor combo meant that the USB Host controller  
interface wasn't able to accurately determine what sort of node it was  
communicating with, and thus the onboard Linux driver tried to treat  
it as a hub node when it was really just a 'terminal' node.  I don't  
have a reference for you on this, just going by memory ..
