CYUSB3033-BZXC uses ThreadX RTOS.
This chip is intended for Mass Storage Application. This can work across all the operating systems: Windows, Linux, Mac and etc.
Are you facing any issue with specific OS?
There is no issue.
I would like to confirm supported OS to make sure.
You said that CYUSB3033-BZXC supports any OS kinds.
Is there a limitation by the version of OS?
There is no limitation of the version of OS w.r.t the CYUSB3033-BZXC.
The device perfomance may vary w.r.t the host driver and applicaiton that are used. This is independent of the CYUSB3033-BZXC.
For example, Windows 10 Mass Storage Driver gives higher throughput than the Windows 7 Mass Storage driver with the same device (CYUSB3033-BZXC).
