For our application we need a number of different usb-devices thus calling for custom udev rules. I have trawled through all topics regarding udev rules and have compiled the test app below. The app has been tested using resin ssh showing that the desired device is not generated. The device gets di…

Hi @mhe_lorenz With the usb device attached, can you ssh into the running container (via the CLI or webterminal), run udevinfo -a -p $(udevinfo -q path -n /dev/tty/USB0) and post the output here?

@lucianbuzzo the command you ask for is not available, so here is the output of an equivalent: root@51361fe:/usr# udevadm info -a -p $(udevadm info -q path -n /dev/ttyUSB0) Udevadm info starts with the device specified by the devpath and then walks up the chain of parent devices. It prints for ev…

any update here? I have several usb serial converters (the same model) that i need to predictably have enumerated using udev rules. i cant get this to work either.

I believe this is the PR that will resolve this issue: https://github.com/resin-os/meta-resin/pull/1206

@nathan Thanks for providing that PR. This is now available in balenaOS, with documentation here: https://github.com/balena-os/meta-balena#udevrules There is also an example of use here: https://github.com/balena-io-playground/gps-tracker

@CameronDiver , this is indeed a great improvement that solves part of my initial problem. However, I need an option to edit the rules “runtime” from a container. Is this possible at the moment?

Hi, you can take a look at this project to achieve inserting udev rule into configuration: https://github.com/balena-io-playground/udev-rule-insert

It seems to do the job from my machine. So to achieve this from a container now, I would need to install the CLI in the container? Although the udev rule was added the device also fell offline and stayed so for 10 minutes until I performed a manual reboot.

Hi @mhe-lorenz, Apologies for the miscommunication, that project is primarily intended to update devices remotely (I don’t know that we’ve ever considered running it from a container!). Taking a step back, would you mind describing a little bit more about how you need to configure these devices, a…

I have no idea whether this is related or not but you should perhaps know that I am also experiencing this issue with the same hardware: https://forums.balena.io/t/gsm-module-crash-on-boot/2418
