Sounds great, but I'm a little bit confused by other information I found

on the web about USB host mode support:
citing from http://www.gp32x.com/board/index.php?showtopic=20717:
  I/O Ports: Headphones, USB (not powered), EXT, DC Power (possibly SDIO

  in the future) *note* it may be possible to use self-powered USB

  peripherals with GP2X, i.e. USB hubs & harddrives etc.
  USB Peripherals: Recent information unfortunately reveals the GP2X

  does NOT feature USB host mode due to the chip implementation used in

  the final design.
Where can I find information on how to make such a EXT adaptor cable

that provides USB host mode IO with current of-the-shelf gp2x?  
TIA.
ciao,
Jacob
