I met some issue，now I used chip named Cypress3014-BZX,The sense that device (Cypress3014) connect to host(USB3.0) with USB3.0 table,when the usb mode is USB3.0,there is no problem.
But I wanted to know,when the usb3.0 table still input,not pull out the table,could the device(cypress3014) change the role to USB2.0 mode?,host was still USB3.0 mode,which could proceed with enumeration in USB 2.0 mode(Cypress3014).
Did someone know some solution about this issue.
If you use the example FW that are available with FX3 SDK, it tries to enumerate in USB 3.0 mode, if not able to enumerate in USB 3.0, then it falls back to USB 2.0 mode. You can disable this feature by making slight modifications in the FW.
Thanks & Regards
