I have been working to get the webtop app working without the docks. You will need a USB 2.0 HS/FS hub that is self powered and you are willing to take it apart to pull pin 4 to pin 5. Instructions coming soon.
Thank you both for the info, I'll be waiting the hub mod (still can't root my phone u.u)
Anw, a modded hub results more practical to get the additional USB ports.
