There is a recently-discovered issue on those systems with USB devices that draw power more heavily. If you plug it in before powering up, it'll be fine, just can't while the system's running. An external drive with its own power supply should be fine. Anything plugged into a powered USB hub is fine. _______________________________________________ pfSense mailing list https://lists.pfsense.org/mailman/listinfo/list Support the project with Gold! https://pfsense.org/gold
