💅 usb_phy_roo...y_disconnect(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — yes the title is literally cut off at usb_phy_roo...y_disconnect(9) and no we're not fixing it, that's just how it's printed, iykyk 🎀

🌸 NAME 🌸

usb_phy_roothub_notify_disconnect — the disconnect notification girlie 💫 she's here to tell you a port peaced out.

---

🦋 SYNOPSIS 🦋

int usb_phy_roothub_notify_disconnect (struct usb_phy_roothub
*phy_roothub , int port );

like, she takes two things and gives you back an int, periodt 💅

---

🎀 ARGUMENTS 🎀

• phy_roothub — the phy of roothub, bestie. only relevant if the host is using a generic phy, so keep that vibe check in mind 🫶
• port — the port index for the disconnect. literally just which port said bye 👋

---

⭐ DESCRIPTION ⭐

so here's the tea: if the phy needs to get connection status, the callback can be used. that's it, that's the whole bit, no cap 🔥

---

💖 RETURN 💖

0 if successful — slay 👑 — and a negative error code otherwise 😭 (yes, negative, we don't do positive errors here)

---

ngl, if you're poking at generic phy connection status from a roothub, this is your girl. go read the kernel file if you want the deep lore 📖✨

and that's a wrap, bestie 🧚💜 this icon dropped from ./drivers/usb/core back in October 2026 — go off, kernel girlies 🍓
