usb_disable_interface(9)

📦 version 7.3.1, in nixpkgs unstable

💅 usb_disable_interface — the "we're SO done with this interface" button

okay bestie, so this is usb_disable_interface from the Kernel API Manual (section 9, iykyk — that's the kernel API girlies) and it does literally exactly what it says on the tin: it disables all endpoints for an interface ✨

🎀 SYNOPSIS 🎀

void usb_disable_interface (struct usb_device *dev , struct
usb_interface *intf , bool reset_hardware );

no cap, that's the whole vibe. returns nothing (void), gives nothing back, just handles it 💅

🦋 ARGUMENTS 🦋

  • dev — the device whose interface is being disabled. like, the actual USB device. the whole main character here 🫶
  • intf — pointer to the interface descriptor. this is the specific interface we're putting on ice, okay?
  • reset_hardware — a flag to erase any endpoint state stored in the controller hardware. like hitting factory reset on the endpoint vibes, ngl. it's a bool, so true = wipe it, false = leave it be 🧚

🌸 DESCRIPTION 🌸

So what it actually does: it disables all the endpoints for the interface's current altsetting. that's it. that's the whole function. it's giving clean-up crew energy 💖

the way it works on the interface's current altsetting is important bestie — not all of them, just the one it's on right now 👑

like yes, that's a LOT of siblings, but they're all iconic in their own way 🍓

and that's the page, bestie 🎀 this cutie came out of ./drivers/usb/core and is dated October 2026 — periodt, go disable some endpoints responsibly 💜
