I know I most likely to be talking to my self but hey someone else may eventualy want help with this.... but I doubt it. anyway the little square ic in that says
phillips
1122a bd
ca2705
ts143d
so I found a philips isp1122a that is a usb stand-alone hub ic. so I found it has some downstream port data- (DM#) and data +(DP#) so I do know there is some resistance on the ic to the brightness board. I may be getting too over my head but now I have a spare board to do tests on so that may help.
