Is there more documentation somewhere on this problem of full speed 
devices on a high speed hub on any site?  I have had issues both in 
Linux and windows when running many full speed devices into a high speed 
hub.  What we have done to fix it was replace the high speed hub with a 
full speed one.  In windows we also noticed if you disabled the EHCI   
problems went away too.   I'll have to give the  "rmmod ehci-hcd" in 
linux a try now too. Thanks!
