But When I didn't unplug this device and reboot Win10. The windows device manager tells me the device is unknown.
When I do this in win7(x64) it works fine.
FX3 Driver version: 1.3.4 or 1.2.3.20
Can anyone help me?

Hello,
This is a known issue with the Bootloader. Please refer to question 2 in this KBA Trouble Shooting Guide for the FX3/FX3S/CX3 Enumeration - KBA222372
You can try cycling the VBUS or use second stage Bootloader as mentioned in the KBA.

Hello,
Can you please manually bind the device to the latest driver in windows 10 from the windows device manager and try rebooting the PC.
Also, let me know what message is reported by the device manager for the device? It is device descriptors failed?

Thank you.
The latest driver which I used is. FX3 driver for windows10
When I reboot 1st time, it works fine. Then 2nd time is failed. Of course, the 3rd time is failed too.
Unknown USB Device (Device Descriptor Failed)
I didn't run any software to use this device.
Just reboot the win10 only.
I did another test with "FX3 DVK Device board REV3" the result is the same.

Hello,
Can you please share a picture of the DVK board which you are using.
Also, please let me know which windows 10 version and host controller you are testing with so that i can try reproducing the same on my side.
Have you tried with a different windows 10 PC? Is it the same case with all windows 10 PC?
