Hi,
I am currently developing a carrier board with compatibility in mind for both Xavier NX and Orin NX.
I am okay without using the DP pins since I never used in the Xavier NX design neither
For the USB SS0(on Orin) the USB1_N, USB1_P plus the USBSS0_RX_N/P USBSS0_TX_N/P are used. As in the Design Guide.
Questions:
1. for the USB_SS1 and USB_SS2 which USB HS pins should be used ?
2. Should the recovery USB be shared with a SS USB? If so will require a switch to change between normal operation and Recovery. Or not?
Much appreciated for any guidance.

On the current Xavier NX design I have the USB2 connected to a switch. (see below).
Would this mean I could not use this USB no longer for the M2 key E interface ?
@kayccc or @suhash : could you please perhaps give your input here? Thanks
