If there is some advantage to devices having a few satoshis, it would be easy to just send them a few satoshis. (Or install a private key that lets them draw a few satoshis from an account you set up for that purpose.)
In other words, you don't need the device itself to do the mining.
And it's always going to be cheaper to produce satoshis in massive mining farms than to do it in tiny chips in embedded devices---so you would always economically prefer to give satoshis to devices, not make them mine the satoshis themselves.
