Hi All, I'm not an OpenMoko guy by any stretch, but definitely a big supporter of open source markets and neat devices like the FreeRunner. Anyways, not sure exactly how things work on the OpenMoko hardware, but over on the Nokia Internet Tablet (the N800) we had a similiar problem in that the hardware supported USB OTG hostmode, but that since the tablets had a MiniB and the OTG standard says that's a big no-no we had to come up with our own solution. I did some reading on the power injection that was required for the Neo, but it sounds like this has been solved on the FreeRunner in the same way the Nokia's do it; have the equipment provide a limited amount of power over the USB bus when placed into host mode.
On the Nokias you can engage host mode by having the ID pin of the mini-B shorted to ground as per the USB OTG specs; I'm not sure if this is true for the FreeRunner hardware, but if it is you may be very interested in the solution we came up with: http://www.electronicproductonline.com/catalog/product_info.php?products_id=1781 Right now I still build and test each of these by hand, but I'm getting manufacturing lined up soon as it's become an extremely popular item (I've sold over 500 so far). Anyways, if anyone reads this and is interested or thinks it might work for the OpenMoko offerings let me know!
