We designed a carrier board for jetson agx xavier but usb didn't work. The following are differences between our carrier board and the demo carrier board. 1. We use USB type A funciton. 2. We usb B55 as USB OTG pin and we connect VBUS_DET to P_3V3 directly. We have already tried the solution from the following link but it's not work. https://devtalk.nvidia.com/default/topic/1047678/jetson-agx-xavier/usb-does-not-working-on-jatson-agx-xavier-/1 Please help us to solve this issue, thanks.
