If I connect to the PowerGuy the old Nokia Connector then the Adapter for the Smaller Nokia Connector and THEN the Nokia Charging Adapter from the old Connector to Micro USB and THEN the whole thing in the N900... THEN it would sometimes charge. Sometimes not. After a couple of times plugging in and out it charges mostly for quite a while. (about 20 or 40 minutes, then it stops charging)
Apparently the USB charging standard has defined that the data pins should be shorted out for dedicated chargers. This is pretty new, so a lot of old chargers won't be doing this, and the N900 will fail to charge.
