question. . .
Cool charger idea! I tried it out and had a question for ya'all. I took apart the USB cable plastic housing and looked at the connections to the treo and there are three contacts going into the treo's power connector: 5V, GND, and a second pin that's tied to GND by the power charger (let's call this pin#2 say). What's been described jumpers 5V from the USB wire over to the power connector but leaves pin2 floating. I wired the 5V over and plugged it into a USB port and wahla it works. However the pin2 looks like it has a pullup to 3.3V inside the treo. It isn't clear what pin2 is used for, but I went ahead and tied it to GND to mimmic the power charger's connections. Anybody know the impact of this pin2?
Gracias
