Good stuff, this is easy to make a charging cable out of any USB to mini USB cable you have lying around... Cut a slit in the cable and just solder a small resistor inline and wrap it back up in some electrical tape or shrink tubing if you can get one to fit.
Good find! Always figured it was something stupid the BB looks for as some car chargers work well for the BB and others do nothing, chargers that aren't BB branded of course.....
I think its only 100ma until something tells the USB port to give more current. That is why it says insufficent power to recharge device when the BB desktop is not installed. When it is, the software recognizes the device and ups it to 500.
Ive never had one to tell me there isnt enough power I dont have the bbdm on this PC and my BB is charging just fine. I dont have any drivers installed either.
I did the same tests on the PC USB port as i did with the desktop power supply. The PC sends out 92mA and without the trigger it shuts down to 0mA. I then put the 2.2M ohm resister across pin 2 and the BB pulled 550mA.
I'd like to add that the test cable i made has not got pin 2 & 3 connected to the PC as its for charging only while i'm on the road. I did the same test with a standard cable and added the resistor which worked as well.
Just another note I'd like to make, most modern electronic devices especially with non-removal batteries will have the charging circuit within the device, eg i know of would be the Sony UX50 and iPod to name a few.

Awesome!! I would LOVE a USB charging cable where I did not have to carry the CD around with me, and all I have to do it plug it in. Someone should market this ... I would SOOO pay for one.

If you send me US$9.99 + postage, I'll post you out a 2c resistor........
