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
