1. USB controller can support as many devices as the USB specs say. I have already get hub working with lpc43xx successfully
2. There is no need for walkaround, but you need to implement hub driver for enumeration
3. I am actually writing my own lib for usb that support the hub, it is due to release in the next couple months (actually it should be already released, but I got stuck into many things lately and have no time to do it.)
If you could not hang on that long, I can send/upload the interim version just for testing the hub mounting.
