Color Which cables do I use to charge Jetbook Color?

There are two with the same pinouts and connectors. One is just straight and the other has a capacitance bulb. There aren't any pictures in either the Start Guide on the PDF User Manual to identify which is which. Plus the scanner pen uses the same mini USB connector, so it's not even clear which cable you use to connect to the computer or the charger.

[Update: I'm guessing from the product pictures that the cable with the capacitance bulb is for the C-Pen, and that you can use any mini-regular USB cable to connect to the charger or the computer.]
