Dear nvidia team:
We have a USB block diagram design as follows:
I read the your jetson official online document introducing USB. USB 3.0 and USB 2.0 must be paired to use, as follows:
As shown in the figure, USB3.0 should be configured as follows:
USB3.0 Port3<-paired->USB2.0 P1
USB3.0 Port2<-paired->USB2.0 P1
USB3.0 Port1<-paired->USB2.0 P1
Device tree:
usb3-0 {
nvidia,usb2-companion = <1>;
status = “okay”;
};
usb3-1 {
nvidia,usb2-companion = <1>;
status = “okay”;
};
usb3-2 {
nvidia,usb2-companion = <1>;
status = “okay”;
};
So is there a problem pairing USB2.0 P1 with three USB3.0 port? Is there any problem when the Typec-C3, Typec-A2 and Typec-A1 devices plugged in at the same time? Does it work normally when Typec-C3 is plugged into a USB3.0 device, and Typec-A2 and Typec-A1 are plugged into USB2.0 at the same time? Please confirm whether there is a risk? Please help me confirm.It is urgent to design schematic.Please help confirm.
Thanks
