uclogic_params_ugee_v2_init(9)

📦 version 7.3.1, in nixpkgs unstable

💅 uclogic_params_ugee_v2_init — a Kernel API Manual moment 🎀

okay so bestie, you're looking at uclogic_params_ugee_v2_init(9) — that's the kernel API manpage, and it's literally about initializing UGEE graphics tablets by discovering their parameters. yep. that's the whole vibe. 🦋

✨ SYNOPSIS ✨

int uclogic_params_ugee_v2_init (struct uclogic_params *params , struct
hid_device *hdev );

like, two args, one int coming back at you. simple. iconic. 💅

🌸 ARGUMENTS 🌸

  • params — the parameters you're filling in, bestie! (and yes, it's to be cleaned with uclogic_params_cleanup later, don't forget 🧹). Not modified in case of error — she's staying untouched, periodt. Cannot be NULL.
  • hdev — the HID device of the tablet interface that you're initializing and getting parameters from. Cannot be NULL.
ngl the "Cannot be NULL" on both of those is doing a LOT of heavy lifting. respect the boundaries. 💀

🔥 DESCRIPTION 🔥

okay so these tablets are internally designed as v2, which is just how they get differentiated from the older models — it's giving "new gen, new me" energy. 👑

what they actually expect is a payload of magic data in order to be switched to the fully functional mode ✨ (yes, magic data, that's the real technical term in this manpage, we don't make the rules), and then they expose their parameters in a similar way to the information present in uclogic_params_pen_init_v1 — but with some differences. highkey similar, lowkey not identical. 🫶

⭐ RETURN ⭐

Zero if successful. A negative errno code on error. no cap. 💖

and that's the whole page, bestie!! 🍓 this one's living in ./drivers/hid, dated October 2026 — so go read it, slay your tablet init, and remember: it's giving kernel API main character energy. periodt. 💖✨🎀
