QUESTION

My ULINK2 worked fine for a week or so, then it suddenly stopped talking to uVision and the Development board. All 3 LEDs flash when it is powered up, but uVision does not see any device attached. When I attach my original ULINK, uVision recognizes it. If I move the ULINK2 adapter to another PC, it works fine.

What would keep ULINK2 from working on one particular PC?

ANSWER

Unlike ULINK, ULINK2 uses and depends on Windows standard USB drivers. Lost communication can happen if your Windows USB drivers have somehow become corrupted.

Try removing and then reinstalling your Windows USB controllers. The following Microsoft Knowledgebase Article discusses the best way to do that.
