hw_usb_set_address(9)

✨ hw_usb_set_address(9) ✨

okay bestie, welcome to hw_usb_set_address from the Kernel API Manual — yes this is a section 9 kernel-function girlie and she's here to set that address. 💅

---

💖 NAME 💖

hw_usb_set_address — configures USB address (execute without interruption) 🫶

---

🎀 SYNOPSIS 🎀

void hw_usb_set_address (struct ci_hdrc *ci , u8 value );

like… that's the whole signature. short and iconic, no notes. ✨

---

🌸 ARGUMENTS 🌸

• ci — the controller. the actual main character here. 👑
• value — the new USB address. the glow-up number you're assigning. 🔥

---

🦋 DESCRIPTION 🦋

so here's the vibe: this function sets the address explicitly, and it does it without the "USBADRA" (advance) feature — because older versions of the controller literally don't support that feature, ngl. so no fancy advance mode, just straight-up explicit setting. slay. 💀

heads up bestie: the NAME section says execute without interruption, so keep that in mind — this one's meant to run undisturbed. 🧚
