✨ NAME ✨

xudc_ep_dequeue — literally removes the request from the queue. that's it. that's the whole vibe. it's giving "yeet the request out of the line" 🎀

🌸 SYNOPSIS 🌸

int xudc_ep_dequeue (struct usb_ep *_ep , struct usb_request *_req );

that's the function signature, copy it EXACTLY, no notes 💖

🦋 ARGUMENTS 🦋

• _ep — pointer to the usb device endpoint structure. like, the endpoint you're messing with. icon behavior only 😌
• _req — pointer to the usb request structure. the actual request that's getting yanked out of the queue. bye bestie 👋
