This is a warning saying that the firmware description for the system is incomplete in case things go wrong later - it is vanishingly unlikely that these devices actually do not require supplies, we'd probably have heard about it if they did. If a supply is not described properly we may for example decide to power off what we think is an unused supply with bad results. [unhandled content-type:application/pgp-signature] | |
