USB_DEVICE_...TERFACE_INFO(9)

💅 USB_DEVICE_...TERFACE_INFO(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's about USB_DEVICE_AND_INTERFACE_INFO, and it's genuinely one of those macros that hits different once it clicks. no cap. ✨

---

🎀 NAME 🎀

USB_DEVICE_AND_INTERFACE_INFO — the macro that describes a specific usb device paired with a class of usb interfaces 🦋

---

🌸 SYNOPSIS 🌸

USB_DEVICE_AND_INTERFACE_INFO (vend , prod , cl , sc , pr );

---

✨ ARGUMENTS ✨

• vend — the 16 bit USB Vendor ID, like the family name of the device 👑
• prod — the 16 bit USB Product ID, the specific model vibe check 🔥
• cl — the bInterfaceClass value 🌈
• sc — the bInterfaceSubClass value 🌸
• pr — the bInterfaceProtocol value 💫

---

💖 DESCRIPTION 💖

So here's the thing, bestie: this macro creates a struct usb_device_id that matches a specific device with a specific class of interfaces. Both. Together. Main character energy. 💅

And it's especially useful when you're explicitly matching devices that have vendor specific bDeviceClass values, but standards-compliant interfaces — like, the device itself is doing its own quirky thing but the interfaces it hands you are perfectly well-behaved. iconic honestly. it's giving "chaotic on the outside, put-together on the inside" 🫶
