I haven't read anything set in stone about 442v2 having USB Host capability, but then it's no mystery on these boards that info is scattered all over the place.
I, for one, hope we get it, but if not, this may be a possible work-around:
The GP2X is like a Linux-based PSP. If this can be done with the GP2X, it should be possible with a 442.
