cyusb3 driver version 220.127.116.11 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.
