MV31 5G driver

Hi
I have a MV31-W CINTERION 5G model on Jetson Xavier NX, according to the official document, I append the following code to $kernel_src/drivers/usb/serial/option.c:
…
#define CINTERION_PRODUCT_MV32 0x00b3
…
{ USB_DEVICE_INTERFACE_CLASS(CINTERION_VENDOR_ID, 0x00b3, 0xff),
.driver_info = RSVD(0) | RSVD(1) | RSVD(3)},

and rebuild kernel. However, this device is still not working, here is my kernel log:
[ 6.744781] usb 2-3.1: new SuperSpeedPlus USB device number 3 using tegra-xusb
[ 6.767781] usb 2-3.1: New USB device found, idVendor=1e2d, idProduct=00b3

[ 6.780815] usb 2-3.1: Enable of device-initiated U1 failed.
[ 6.784078] usb 2-3.1: Enable of device-initiated U2 failed.
Is any ideas to setup this device driver?
Thenk you

Hi,

Is such “official document” provided by your 5G device vendor? Because I don’t think we have such document…

Hi,

Please also modify below driver in the config file to =y in the tegra_defconfig.

958 CONFIG_USB_SERIAL=y
959 CONFIG_USB_SERIAL_CH341=m
960 CONFIG_USB_SERIAL_CP210X=m
961 CONFIG_USB_SERIAL_FTDI_SIO=m
962 CONFIG_USB_SERIAL_PL2303=m
963 CONFIG_USB_SERIAL_OPTION=m

Hi,
Thanks for reply.
The driver document “MV31 USB model startup guide for Linux.pdf” is provided by my device agent. I alos configured the tegra_defconfig as follows:
958 CONFIG_USB_SERIAL=y
959 CONFIG_USB_SERIAL_CH341=m
960 CONFIG_USB_SERIAL_CP210X=m
961 CONFIG_USB_SERIAL_FTDI_SIO=m
962 CONFIG_USB_SERIAL_PL2303=m
963 CONFIG_USB_SERIAL_OPTION=m
however, the 5G device is still not working.

Hi, WayneWWW
Thanks for your support. My 5G device is working now, but I got a new problem: After my device is dial up and connected to internet, ping 8.8.8.8 will fail (no response) after 30 ~ 40 seconds. But the device state in the system is “connected”, is any ideas to resolve this problem?
Thanks very much.

We don’t have 5G modem to try, you may contact with vendor. Thanks
