I tried different USB cables, including the one that came with the device, directly from the PC. I use them daily for ST boards, so I know the cables are fine.
I last used the Discovery two years ago and it was fine. I didn't touch it since then, and now nothing happens. This is on both Windows and Linux, on different PC's. I wiggled the cable in case a connection in the Discovery is bad, but still nothing.
Is there anything I can do, or is this it... end of line?
