STRUCT HID_SENSOR_HUB_DEVICE(9)

✨ struct hid_sensor_hub_device(9) ✨

okay so bestie, this is a page from the Kernel API Manual — yes, the kernel manual, we're doing this, we're built different 💅 — and it's all about struct hid_sensor_hub_device, which is literally the place where the hub instance data lives. like, that's its whole job. storing the hub instance data. iconic behavior honestly 👑

---

🌸 NAME 🌸

struct hid_sensor_hub_device — stores the hub instance data 🫶

---

🦋 SYNOPSIS 🦋

okay so here's the whole struct, laid out for you, no cap, character for character:

struct hid_sensor_hub_device {
    struct hid_device *hdev;
    u32 vendor_id;
    u32 product_id;
    u32 usage;
    int start_collection_index;
    int end_collection_index;
    struct mutex *mutex_ptr;
    struct sensor_hub_pending pending;
 };

look at her. gorgeous. every field accounted for 🎀

🧚 Members 🧚

let's do a little vibe check on each field, one by one, because they all matter:

• hdev — stores the hid instance. that's it, that's the whole thing 💖
• vendor_id — the vendor id of the hub device. who made it, basically 🏷️
• product_id — the product id of the hub device. which one it is 🌈
• usage — the usage id for this hub device instance. iykyk ✨
• start_collection_index — the starting index for a phy type collection. where the collection begins, bestie 📍
• end_collection_index — the last index for a phy type collection. where it wraps up, periodt 🏁
• mutex_ptr — synchronizing mutex pointer. yes, a pointer to the mutex, not the mutex itself. we love a pointer to a lock 🔒
• pending — holds information of the pending sync read request. the "wait, we're still waiting on that" info 🙈

quick reminder bestie: this page lives at ./include/linux and it's dated October 2026 — that's the source, the version vibe, and the date all in one 🎀

k byeeee, go read your structs, mwah 💋🦋✨
