I need to build a baseboard for an Overo Firestorm that is much like a Tobi, but it needs a 7 port USB hub built into it.  I am using the SMSC USB2517 for this, but I am pretty new to USB hardware.  So far, when I plug the USB hub evaluation board into my Tobi, and it works great with kernel 2.6.  

I suppose I can just copy the Tobi schematic onto my own design... but I am a little hesitant to think it could be that simple.  Does anyone have any experience with USB hardware?  I can offer some compensation for any design consultation time or troubleshooting.  I'd hate to waste money on a board because there was some trick I didn't know.
