ehci_xilinx_..._handed_over(9)

💅 ehci_xilinx_..._handed_over(9) — like, the Kernel API Manual page, bestie 🎀

okay so this is a page from the Kernel API Manual and it's literally called ehci_xilinx_..._handed_over(9) — yes the ellipsis is part of the name, she's mysterious like that ✨

---

🌸 NAME 🌸

ehci_xilinx_port_handed_over — hands the port out if it failed to enable it. that's the whole vibe fr fr 🫶

---

✨ SYNOPSIS ✨

int ehci_xilinx_port_handed_over (struct usb_hcd *hcd , int portnum );

like, that's the whole signature, no notes 👑

---

🦋 ARGUMENTS 🦋

• hcd — pointer to the usb_hcd device that the host controller bound to. it's giving "which controller are we even talking about" energy 💫
• portnum — the port number the device is attached to. gotta know which port, obviously 🙈

---

💖 DESCRIPTION 💖

so this function is basically a little spot where we tell the user that the Xilinx USB host controller does support LS devices. and in an HS-only configuration, it does not support FS devices either. it's hoped that this can help a confused user 😭 because bestie, confusion is real and we're here to help 🫶

now, there are cases where the host controller fails to enable the port due to — for example — insufficient power that can be supplied to the device from the USB bus 🔌💀. and in those cases? the messages printed here are not helpful. yeah. iconic of us. ngl that's a warning worth knowing ⚠️

🌈 RETURN 🌈

Always returns 0. always. no cap, every single time 💅✨
