We've got a Windows 8 machine we're testing with.  When we try to perform SuperSpeed IN transfers from EP0 of the FX3, if the transfer is larger than the 512-bytes (the only EP0 packet size supported for SuperSpeed), the transfer times out.  We can see this on our USB analyzer and the call fails in Windows.

We are not seeing this issue with Windows 7.  Has anyone seen this behavior?

they already discussed that issue and microsoft has a workaround in next release of Windows 8.
