Hello, Thanks for thread. Looks like mine ferrites (FB18, 19 are blown) So I removed their remainings. Rest seems to be complete now. Unfortunatelly after first measurements done (no shortcuts in powerlines) and replacing blown ftdi chip with new one. There is no reaction for plugging USB cable. No device detected, no voltage any where. Seems for soldering issue or damaged power switch. Gonna inveatigate it Later. Temporarry, AD2 should run without FB18 and 19?

Hello everyone! I found one seriously damaged AD2 and I would like to try fix it. So my problem is missing conponents around ft232hq (someone before me was trying to fix it because original ft232hq has burnt out hole in its surface.) Before I replace ft232hq with new original one (I know it must be programmed) I would like to take some on board measurements and clarify which components are missing (some have evaporated, some have been removed) and what can be potentionally damaged. So maybe You guys know exact diagram of ft232hq part? It seems to be typical application for ft232hq (looks like typical from ft232hq datasheet) but there are little differences (TVS diodes close to usb connector etc). Thanks! :)
