Thought i would share my solution to charging the Blackberry from a USB port (PC or USB portable Charger) without DRIVERS!!!!
I could not work out for the life of me how the 2 drivers triggered the PC USB port to charge the Blackberry until now. They trigger a "turn on" supply to pin 2 of the USB cable which the Blackberry Unit sees and turns on its on board charging circuit.
I played around with some spare USB cables, resistors, power supplies and have found a solution to charge the BB from any USB port (PC) or from any portable USB charger.
The secret is this......are you ready......all you need is a bleed resister across pin 1 (positive) and pin 2 (white core of USB cable) and thats it. Your BB will charge without the warning message and with the lightning bolt.
