Same problem, debbuger breaks when trying to get the registry key with invalid 
key.

I temporarily fixed with this code in  getDeviceDetailsWin() function:

    HKEY devKey = ::SetupDiOpenDevRegKey(devInfo, devData, DICS_FLAG_GLOBAL, 0, DIREG_DEV, KEY_QUERY_VALUE);
    if (devKey == INVALID_HANDLE_VALUE) {
        return false;
    }
