Hi,

   

CY_U3P_USB_EVENT_RESET event comes only when there is a bus reset.

   

Yes, you observe two reset events when you download the firmware into FX3. first one is during the connection to USB host (this happens immediately after downloading the firmware) and second one happens when host assigns a new address to it.

   

Thanks,

我在win10下使用FX3 USB3.0 通过UVC传输视频数据,在识别设备时CY_U3P_USB_EVENT_RESET一直触发(通过BusHound可以看到GET_INFO后,设备没有IN数据回复), 并且设备识别不成功。过一点时间(通过BusHound可以看到GET_INFO后,设备IN数据回复),设备可以识别,但是通过相机打开设备时,设备又重复枚举了。除此之外,win10 USB2.0正常,win7下USB3.0 、USB2.0都正常。
