hdm_probe(9)

💅 hdm_probe 💅

okay so this is hdm_probe(9) from the Kernel API Manual — section 9, kernel API territory, bestie, this is the deep end and we're swimming 🫶

---

✨ NAME ✨

hdm_probe — the probe function of the USB device driver, no cap 💖

---

🌸 SYNOPSIS 🌸

int hdm_probe (struct usb_interface *interface , const struct
usb_device_id *id );

like literally that's the whole signature, she's not complicated ✨

---

🎀 ARGUMENTS 🎀

• interface — the interface of the attached USB device. yes, the interface, the one that just showed up 💫
• id — a pointer to the USB ID table. she's pointing at the table, iconic behavior 👑

---

🦋 DESCRIPTION 🦋

so what does she actually do? bestie, she does everything in one go, main character energy fr fr 🔥

she allocates and initializes the device instance, then adds the new entry to the internal list, then scans the USB descriptors, and then registers the interface with the core. that's a lot for one function and she ate 💅

but wait, there's more — additionally, the DCI objects are created and the hardware is sync'd. the way she just... creates objects and syncs hardware like it's nothing 😭✨

return 0 on success. in case of an error a negative number is returned — so if you see anything below zero, that's a vibe check that did NOT pass, and you should go look at it 🙈
