I have 1.2.3.20.  With the last Windows 10 Update 2004 our USB communication has degraded on certain hardware.  Anyone else have similar issues?  If there is a newer version where would I find it?

Thank you.

Hello,

Please check the Streamer Application from the FX3 SDK which uses CyAPI.lib for cpp and CyUSB.dll for C# and queues up the data transfers depending upon the parameters set in the applications.

Hello,

cyusb3 driver version 1.2.3.20 is the latest one.

Can you please let me know the issues you are facing in detail?

We have a continuous thread that reads via IOCTL_ADAPT_SEND_NON_EP0_DIRECT overlapped with a 200mS timeout. The device is making ready a new endpoint report every 10mS, in that report we have a clock. At random intervals (computer dependent) we see dropouts that indicate an elapsed time based on the clock in the report between successful reads of over 1 second.
