View Full Version : USB Charger cable ID pin resistor - need help from someone with a multimeter

Hey guys,

As we know Atom doesn't charge with other chargers while it's on, unless you hack a cable to connect miniusb ID pin to gnd.

I've lost my charger. Does anybody know or can test to see the resistance value of the ID pin? Some call it 'pin 4' on mini-usb, but actually it doesn't have a number and the next pin is numbered 4

The ID pin may be directly connected to GND, or may have a resistor between gnd. I need to know it to make/find a more original-like cable.

Also, does anybody know how HP rw68xx handles this with a charger with unpluggable usb cable? Does it require using a special cable with modified mini usb socket for wall charger? Cause there is no equivalent pin for the ID pin, on a standard usb socket, so probably there is no identification function on the charger.

Edit:
I'll try to locate a working cable / usb-miniusb adapter on dealextreme, if you know a specific item which should work, that would be even better.

Thanks
