1) We are in process of developing a driver of windows 10 and it will be launched soon. But the timeline is not confirmed yet,
2) Please record a USB Trace and check what is goin wrong with the Interl On Board Host.

I'm sure you and your team are busy dealing with some of the new hurdles presented by the new Windows 10 driver signing requirements.   
I realize you may not have all the answers right now, but do you think Cypress will be able to provide its FX3 customers some advice on re-distributing your upcoming Windows 10 driver, after changing the VID/PID in CyUSB3.INF (per the CyUSB3.sys programmer's reference.)
From my understanding (correct me if I'm wrong!), Windows 10 will require developers to get an EV cert, which includes uploading drivers package to the sysdev portal and signing some sort of "attestation agreement" saying you've tested the driver. Cross-signing will no longer suffice.
Since your team is inevitably going through this, any chance you could add some notes on this to future releases to the CyUSB3.sys Programmer's Reference?
For those of us that use the CyUSB3.sys and only add our device's VID/PID and re-sign, this new driver signing sounds like it's going to be a painful experience...
It got to be a hard work to build the new driver. Do you have any idea about when it will be released? I just upgraded to win 10, deleted windows.old(which is essential to get back to win8), and found that I am not able to use the device..... I should have checked this... (mad at myself)
Have you release the FX3 driver for win10 and how to get it ？
Please create a technical support case for getting the Windows 10 driver for FX3.
The associated page (drivers-ez-usb-fx1-and-fx2lp-kba94413) does not explicitely mention FX3. So are you sure that it concerns both FX2LP and FX3 ?
Yes, It can be used with all FX1/FX2/FX3
Do the Win 10 drivers for FX2LP/FX3 pass the Windows-Hardware-Lab-Kit (HLK) Tests ?
Do you know if these version 1.2.3 drivers work with Windows 10 beyond version 1607? More specifically, can they be signed by the Dev Portal with Extended Validation after updating the .inf file to reference my device?
For what it's worth, we are using these drivers with no issue on Windows 10 Creator's Update. (Version 1703).
