Problem with EM05-E on Jetson Orin NX

Hello,

I am trying to use a EM05-E module on a Jetson Orin NX board.

dmesg output:

[   14.189621] option: unknown parameter 'vendor' ignored
[   14.189629] option: unknown parameter 'product' ignored
[   14.189808] usbcore: registered new interface driver option

lsusb output:

Bus 001 Device 003: ID 2c7c:0125 Quectel Wireless Solutions Co., Ltd. EC25 LTE modem

lsusb -t output:

/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/4p, 480M
    |__ Port 2: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M
        |__ Port 3: Dev 3, If 0, Class=Vendor Specific Class, Driver=option, 480M

A single port (ttyUSB0) is being recognized. Would it be possible for you to help me understand what is happening?

Kind regards

It seems the modem is in dump state. It didn’t boot up successfully. Something wrong happened.
