xudc_done — the function that Exeutes the endpoint data transfer completion tasks. Bestie, yes, Exeutes is literally the spelling on the page, and we are keeping it exactly. 💅

🦋 SYNOPSIS 🦋

🌸 ARGUMENTS 🌸

• ep — pointer to the usb device endpoint structure.
• req — pointer to the usb request structure.

Okay so here’s the whole moment: it deletes the message from the queue and updates the data transfer completion status. That’s the assignment, and it ate. Queue message gone, completion status updated — iconic cleanup behavior. ✨
