USB Superspeed Peripherals

[AvOm_4629506]

Good day, gentlemen and ladies. I have a problem with USB3 on CX3. I used CyU3PUsbInitEventLog and CyU3PUsbGetEventLogIndex to understand why USB 3 is being disabled and this is what I got:

0x6 CYU3P_USB_LOG_USB3_PHY_ON Indicates that the 3.0 PHY has been turned on

0x10 CYU3P_USB_LOG_USBSS_DISCONNECT Indicates that the USB 3.0 link has been disabled

0x4 CYU3P_USB_LOG_USB3_PHY_OFF Indicates that the 3.0 PHY has been turned off

0x5 CYU3P_USB_LOG_USB2_PHY_ON  Indicates that the 2.0 PHY has been turned on

0x40 CYU3P_USB_LOG_USB2_SUSP  Indicates that a USB 2.0 suspend condition has been detected

0x41 CYU3P_USB_LOG_USB2_RESET Indicates that a USB 2.0 bus reset has been detected

0x51 CYU3P_USB_LOG_USBSS_ENABLE Indicates that a USB 3.0 connection is being attempted again

0x42 CYU3P_USB_LOG_USB2_HSGRANT Indicates that the USB High-Speed handshake has been completed

0x10 CYU3P_USB_LOG_USBSS_DISCONNECT Indicates that the USB 3.0 link has been disabled

0x46 CYU3P_USB_LOG_USB2_SETCONF Indicates that USB configuration has been selected

0x40 CYU3P_USB_LOG_USB2_SUSP  Indicates that a USB 2.0 suspend condition has been detected

0x41 CYU3P_USB_LOG_USB2_RESET Indicates that a USB 2.0 bus reset has been detected

0x51 CYU3P_USB_LOG_USBSS_ENABLE Indicates that a USB 3.0 connection is being attempted again

0x42 CYU3P_USB_LOG_USB2_HSGRANT Indicates that the USB High-Speed handshake has been completed

0x10 CYU3P_USB_LOG_USBSS_DISCONNECT Indicates that the USB 3.0 link has been disabled

0x46 CYU3P_USB_LOG_USB2_SETCONF Indicates that USB configuration has been selected

what can this be related to?

I use exactly the USB 3 Port since I have USB 3 devices and they connect to it normally
