usb_enable_endpoint(9)

💖 NAME 💖

usb_enable_endpoint — bestie, this is the one that turns an endpoint ON for USB communications ✨

So this page lives in the Kernel API Manual, and ngl it's a tiny little function with a big job: getting your endpoint ready to actually talk. 🫶

---

🌸 SYNOPSIS 🌸

void usb_enable_endpoint (struct usb_device *dev , struct usb_host_endpoint *ep , bool reset_ep );

---

🎀 ARGUMENTS 🎀

• dev — the device whose interface is being enabled 👑 like, the whole device, the main character here
• ep — the endpoint, i.e. the actual thing we're enabling 💅
• reset_ep — a flag that says whether to reset the endpoint state 😭 yes or no, that's the vibe check

---

🦋 DESCRIPTION 🦋

Okay so here's the tea: it resets the endpoint state if you asked it to (that's reset_ep doing its thing), and then it sets the dev->ep_{in,out} pointers. 📍

And for control endpoints, it handles both the input and the output sides — no picking favorites, both get loved on 💖✨
