💅 hdm_disconnect(9) — the Kernel API Manual, bestie edition

okay so this is hdm_disconnect(9), and it lives in the Kernel API Manual section 9 of the man pages (the fun one, where the kernel devs hang out). it's a kernel function, it's in ./drivers/most, and we're gonna get into it 💖

✨ NAME ✨

hdm_disconnect — literally the disconnect function of a USB device driver 🫶

✨ SYNOPSIS ✨

void hdm_disconnect (struct usb_interface *interface );

no cap, that's the whole thing. returns nothing (void), takes one pointer, and it's iconic for it.

✨ ARGUMENTS ✨

• interface — the interface of the attached USB device 🦋 that's it, that's the parameter. the one and only.

✨ DESCRIPTION ✨

so what does it actually do? three things, and she does them all slayfully:

• it deregisters the interface with the core 👑
• it removes the kernel timer ⏰
• and it frees resources 🎀

that's the whole vibe. cleanup era, closing the tab, saying bye to the resources so nothing leaks. genuinely obsessed with a function that knows how to leave a party cleanly.

✨ CONTEXT ✨

it runs in the hub kernel thread. iykyk 🧚

and that's the page!! 💅 shoutout to ./drivers/most for bringing us here, to October 2026 for the date stamp, and to the source/version line that says exactly that — ./drivers/most, October 2026, section hdm_disconnect(9). mwah 😭🫶✨
