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.

too much trouble just hit cancel on the install and it will still charge
