Anyway we will take care that charging is controllable by software just like it is on N900.
Please check other threads in this forum about fastcharger detection and D+/-_short

Throwing in my tuppence for what it's worth, my N900 gives me the most grief when dealing with modern chargers designed for the resistor-style phones everyone has now. Basically, it just doesn't charge unless I use a really dumb charger, even when I cut the data lines completely. If the Neo900 could be a little more..."robust" it would be much appreciated! I suspect the problem is with the "play dead" state of the phone, as most decent chargers alter their state based upon what's plugged in...and so does the N900, so they cancel each other out once the N900 boots past the hardware charging state. Every other device I have works with my chargers just fine...

...but yeah, if the Neo900 could be more robust, that'd be great
