✨ usb_hcd_reset_endpoint(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 — yes, that's the manual name, and yes, this page is tiny but it matters, so let's get into it 🫶

🌸 NAME 🌸

usb_hcd_reset_endpoint — reset host endpoint state 💅

---

🦋 SYNOPSIS 🦋

void usb_hcd_reset_endpoint (struct usb_device *udev , struct
usb_host_endpoint *ep );

literally that's the whole signature, no cap. it returns void, so don't go looking for a return value, there isn't one ✨

---

🎀 ARGUMENTS 🎀

• udev — the USB device. you know, the actual thing plugged in 🔌
• ep — the endpoint to reset. this is the one getting the glow-up 💅

---

💜 DESCRIPTION 💜

so what does it do?? it resets any host endpoint state — like:

• the toggle bit
• the sequence number
• the current window

that's it, that's the whole job. lowkey iconic for how short it is 🧚
