USB OTG on the iriver h3xx

[threepointone]

I'm not sure exactly why rockbox hasn't been able to get USB OTG working on the iriver h3xx, but if it relates to the hardware (the USB schematic seems to be missing from the schematics section), this application note on SCF5249/ISP1362 interfacing might be of interest: http://www.freescale.com/files/32bit/doc/app_note/AN2645.pdf
It could help in figuring out how the ISP1362 is connected in the iRiver, if that's the problem. It might also shed some light on the differences between the international and US versions of the iRiver which disable USB OTG

It's mainly because no-one had a go at doing it. Now someone is working on USB for us as part of Google Summer of Code - so hang in there!
