The latest version of cyusb3.sys released is 18.104.22.168. Please let us know why do you want to have an older version?
I am having issues using the firmware on Win10 machines. The firmware works perfect on win7, but I am using version 22.214.171.124. Can you provide me the same firmware version to test on the windows 10 machine?
Can you please elaborate what is the issue that is seen with the latest driver? Meanwhile I will check internally for the driver version 126.96.36.199.
When I use the same firmware + sw + hardware on a windows 7 machine I can get data with 0 failures(no drop in data). But on that windows 7 machine I am using driver 188.8.131.52. When I move the same firmware + sw + hardware to a windows 10 machine and using driver 184.108.40.206 I get a lot lost data. Meaning I am not getting the number of data I am expecting. The only difference is the OS and the driver version. Can you provide me with the 220.127.116.11 driver? Thank you.
The driver version 18.104.22.168 is not certified for Windows 10. The driver version 22.214.171.124 is Universal driver which is certified for Windows 7 and Windows 10. Also, we do not recommend to use an older version of driver for development as newer versions perform better compared to older ones.
Please let us know more about your application so that we can understand the cause of failure. What is the type of data transfer? Is it bulk or interrupt or isoc? If possible, can you please test the data transfer with the streamer application and share a snapshot for us to check?
