Can you give a bit more details on the crash itself, ie where it occurs? |

I'm not sure what you are requesting but I will attempt to answer. When operating the HidDemo board from CCS, all is well until I press the Reset button on the demo board which causes an immediate crash which occurs at line 154 of DevReader.pas which is in jvcl\examples\JvHIDController\ReadWriteDemo. In my original issue I noted not only the code in the area of the error as supplied, but the simple code change that would (and did) fix the problem. In lay speak, don't try to set a device nil when the device doesn't exist. Hope this helps, please let me know if I didn't actually answer your question. |

Please try again with the current GIT/daily content, I'm not seeing this code at all |
