I made FX3 firmware for UVC over ISO endpoint on USB 3.0. It is working on Windows 8, Linux and MacOS, but doesn't work on Windows 7 (doesn't even start stream). I suspect that UVC class driver on Windows 7 doesn't support burst on ISO, but I cannot find any information about that. Is there any information about that or has anyone tried that?

Which UVC spec do you following? UVC1.5?
If yes, Windows7 cannot support UVC 1.5, you can refer to the microsoft web:https://msdn.microsoft.com/en-us/library/windows/hardware/ff568651%28v=vs.85%29.aspx

No, I was following UVC 1.1 specification.
I tried Cypress UVC iso example and it also doesn't work on Windows 7.

Hi,
with windows 7 what connection mode you want to use ? if your transfer requires a superspeed mode, forget it under windows 7 because Windows 7 usb stack doesn't natively support usb 3.0.
Hope this will help.
BR.

Yes, I'm using superspeed endpoint, but it is working with BULK endpoint.
I also tested bandwidth with Cypress Streamer application and ISO endpoint and I got much more bandwidth then I need.

We believe it is a limitation with the uvc driver on Win7.
