What should we look at to find out what speed it wants to operate at? We didn't 
look into it becuaase the real problem, from our perspective, was that the 64ms 
interval was being honoured by the host when it should be the 10ms as is 
literally in the endpoint descriptor. Our assumption was that since it says 
it's USB 2.0 then bInterval must be intterpreted in light of that regardless of 
the actual speed used for communication.
