Huawei Cellular Dongle on Jetson TX2

Product support
1

Hello everyone,

I started testing out nvidia Jetson TX2 and found out that usb_modeswitch doesn’t seem to work the same way as it does in other Resin support hardware boards:

When plugging in the a Huawei modem or when booting with modem plugged in, it stays in default modem and doesn’t not appear in modem manager list:

I can find the 12d1:14fe ID in /usr/share/usb_modeswitch but it looks like these rules aren’t taken into consideration

Hello @eblex,

Have you tested your configuration with our cellular test project? It’s available at: https://github.com/resin-io-projects/cellular-test

Could you try running it and report back what happens?

Hi @abrodersen

Same thing with this project, the modem doesn’t switch.

It seems to be OS level related rather than something we can do in the container

Hi,
This modem has a bit of an issue with the udev rules. I managed to make it work by manually running usb_modeswithc -v 12d1 -p 14ef -J after this the modem worked just fine. I will push a fix in the new release of the TX2 which will be out later today.
Kind regards,
Theodor

I was unable to find a proper fix and due to the fact that the issue is also present on the Ubuntu distribution that Nvidia provides we will delay this bugfix for a further release.
We apologize for any inconvenience.
Kind regards,
Theodor
