USB0 can't use mouse and key after login

[jb035.cheng]

We made a customized Orin NX carrier board, and used USB0 for entering recovery mode to program NVME SSD.
How to let the USB0 can use the mouse and keyboard after programming and login into GUI ?

Hi,
You would need to modify device tree to fit the hardware design. Is the USB0 designed as a type-A port? Looks like you expect the port to run in host mode only so it seems to be a type-A port.

Yes, it a type-A port.
If I cahnge the xusb_padctl@3520000.ports.usb2-0.mode from otg to host, the flash process wil fail by timeout(flash_1-3_0_20230630-141333_usb0_host.log).
The flash command is ./tools/kernel_flash/l4t_initrd_flash.sh --keep --external-device nvme0n1p1
-c tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/t186ref/cfg/flash_t234_qspi.xml”

I found my question is duplicated with

USB host enable along with NVMe flashing in Orin NX

Hi, thanks for the clarification. I think it is expected that flashing with USB2-0 configured as host would fail, because you cannot establish connection between the host PC and the device now. Did the two steps method in your previous reply also result in timeout? Have you tried to flash first with the default OTG device tree, then boot into the system to replace the device tree with the host mode one?
