Thanks for the reply. The link about migration that you have suggested just mentions about the "New CyUSB.dll" and does not mention anything about the version number. It is just the version number that leads us to the confusion.
So would you say CyUSB.dll version 18.104.22.168 is the latest version of the dll? Could you also kindly comment on the thread safety aspect of this new dll, nothing is mentioned about this in the documentation. Thanks.
Did this get resolved? I am getting crashes in a multi-threaded application, that seem to be related to calls to GetOverlappedResult.
The problem is, I am using 4 EP, and without threads or with lock() in the C# application, the performance is really bad. So I need them.
