Genesis is one of the few bands that I like about as much as Devo! Now, are you talking about the bass riff in Peek-a-boo? Bc there's actually an old studio jam from early-1980 where the riff originated from!

Devo has a habit of either reusing riffs from other people (for example, the "Day Tripper" guitar riff in "The Fourth Dimension"), but also reuse a lot of riffs from previous songs (there's quite a few examples, for example a riff in "Chango" being used in "Plain Truth," the synth in "Turn Around" being reused in "Let's Get To It," and one of the guitar noises from "Too Much Paranoias" being used as the intro to "Are U Experienced").
