👋

I’m currently doing a round of updates on the [USB Device Plugin](https://gitlab.com/CarbonCollins/nomad-usb-device-plugin) (long overdue I know), however have run into a question on what versions of Nomad that the plugin is able to support.

The [v0.2.0](https://gitlab.com/CarbonCollins/nomad-usb-device-plugin/-/releases/0.2.0) of the usb device plugin supported Nomad 0.9+ (mostly due to that being set in the [Nomad Skeleton Device Plugin](https://github.com/hashicorp/nomad-skeleton-device-plugin)), however, during this round of updates I had also updated the Nomad dependency to use Nomad 1.3.1 which is where my question is. Am I still able to support Nomad 0.9 onwards as it seems that the device driver API has not had its version updated from the initial v0.1.0 released with Nomad 0.9

Thanks!

Hi @CarbonCollins! Indeed there hasn’t been much innovation happening in Nomad’s device driver API - I wouldn’t expect any breakage since 0.9.

There _maybe_ something interesting around cgroups v2 which Nomad v1.3 now supports - but that’d be specific to whatever the driver is doing.

Cool,

The cgroups stuff might be something I will need to try out then 🙂

For now though the readme in the driver is still correct!

Thanks!
