Our device has a Type-C connector and should be connected to a computer with legacy USB or Type-C interface, so we installed a switch and CC controller. The circuit is similar to the one in figure 2, but with a separate CC controller. The software solution is interesting, but I did not find a link to it.
The first problem is that the active switch has a built-in automatic receiver termination detection and a connection at super speed is determined between it and the FX3, but in fact the connection to USB 2.0 and there is no connection. I decided to cancel it checking the electrical compatibility. Began to work on USB 2.0.
But the connection is not established at super speed if connection to USB 3.0.
Do you mean that you are facing problems about the USB 3.0 path? If so, do you have any update?
Is it due to the defect of hardware design?
Hi, I have the latest version 1.3.4 of the developer kit. As I wrote in the first post in my design, an external CC controller and active switch are used. Without a controller and a switch, everything works fine. I think you will not be able to help me, because I decided to stop using the active switch, and everything will work.
Okay, I get that.
