# can.setup

> One-time CAN bus setup for the Almond Axol Hub.

One-time setup for the Almond Axol Hub (dual-channel USB CAN adapter). Installs the `gs_usb` kernel driver if the kernel lacks it (see [`can.driver`](/cli/can-driver) — needed on NVIDIA Jetson / ZED Box), writes persistent udev rules, assigns fixed interface names, registers a startup script in the root crontab, and brings up the interfaces immediately.

* Left arm → `can_alm_axol_l`
* Right arm → `can_alm_axol_r`

```bash theme={null}
axol can.setup
```

<Note>
  `sudo` will be invoked automatically where required.
</Note>

<Info>
  After setup, the interfaces come up automatically on every reboot (via a `@reboot` cron hook). If the Axol Hub is re-plugged mid-session without a restart, bring the interfaces back up with [`can.enable`](/cli/can-enable).
