Looking for USB host pads
I am looking for the (internal) USB host connection on a Kindle Paperwhite 2 (I believe the PW3 would be identical). This supposedly should be near the SIM card / 3G module connector. On the KT at least there seems to be two pads (see https://www.mobileread.com/forums/sho...&postcount=159 and https://www.mobileread.com/forums/sho...&postcount=166)

On the PW2, the board layout is different. I have found a good connection for power, but I have no clue which of the pads could be the two data lines for USB.

I've annoted the picture from https://www.mobileread.com/forums/sho...d.php?t=229223 with what I know so far. The cyan dots mark pads that are GND.

Does anybody know where (or if) DATA+ and DATA- are available on an open Kindle Paperwhite 2 (rev 11), or could make an educated guess based on the image? Alternatively I would also appreciate any hints on how to figure this out myself.

TIA
