The callback should return right away. I wasn't sending anything funny to the out stream.

Here's the callback method signature:

DWORD __stdcall HandleDataEvent(UCHAR *pData, DWORD deviceID, DWORD error) ^^^^^^^^^

and here's how I implemented it:

public interface PedalCallback extends Callback

^^^^^^^^ Your callback signatures don't match calling convention. So when your callback returns, you've corrupted the stack. Use StdCallCallback instead.
