🎀 NAME 🎀

like, that's the whole NAME section. short, sweet, no cap. it clears the device selfpowered feature and we move. 💖

✨ SYNOPSIS ✨

the signature, exactly as it appears:

🫶 ARGUMENTS 🫶

one argument, bestie:

🌸 DESCRIPTION 🌸

okay so here's the vibe: this affects the device status reported by the hardware driver. some hardware may not support bus-powered operation, in which case this feature's value can never change. that's the hardware's whole lane, and the value is locked in like that. 🙈
