+
+## Troubleshooting
+
+If you are running a {% term "Home Assistant Core" %} or {% term "Home Assistant Container" %} installation: Depending on your system configuration, it may be necessary to grant explicit user access rights to the USB device by creating an udev rule.
+
+{% details "Creating an udev rule" %}
+
+1. Find the *vendor_id* and *product_id* of the USB device by calling `lsusb`:
+
+```bash
+lsusb
+
+#e.g.: Bus 001 Device 005: ID 04b4:fd15 Cypress Semiconductor Corp. Energenie EG-PMS2
+```
+
+2. Create an udev rule by calling:
+
+```bash
+sudo echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="04b4", ATTR{idProduct}=="fd15", MODE="0666"' > /lib/udev/rules.d/60-energenie-usb.rules
+sudo udevadm control --reload-rules
+sudo udevadm trigger
+```
+
+{% enddetails %}
