Well it sounds a bit out of place to say it, but: great.  At least we
understand what's happening.

A wall charger doesn't try to talk with the device over USB, it is
recognized by a magic resistor on the USB ID pin, that's why it works
but host charging didn't.

I made patches to reduce the probability of this from 50:50 to ~10% and
just sent them out, I didn't find how to eliminate it yet.

| Which uboot is "safe"?

I'm not sure.  I suspect older U-Boot had lower probability of making
the same problem since we had no idea this was happening until now, and
some of the fixes I added would have been needed on older versions too.
~ best bet is to update to tomorrow's U-Boot and we'll try to remove the
remaining chance of the problem in the meanwhile.
