Hi
I have USB drive 32G, but it had fallen in snow and stayd in there for few hours, until I had discovered its missing and then search and found.
But it didnt work, though I didnt try to run it until I had dryed it for 12 hours.
Still no luck and I have opened it and checked for probable causes, but there was none. At first I suspect quartz 12 MHz, but I checked it with my osc. and there on one end is a 12 MHz, BUT it is almoust perfect sine wave and p-p is around 3 volts. Does anyone know, is this normal?
So I assumed, that quarz is running and checked these USB inputs, there are two data lines, probably clock and data I suspect, I m not familiare with USB. So there is no activity in there, and I checked two resistor-like objects on both of these data lines path, and there seems to be no conductivity. Markings are RM1 and RM2, as can be seen from photo.
Does anyone know, what is excactly their nature? And can I bypass them by solder. I suspect that they are some barriers to protect for static or something.
Any help is welcome.
