USB_VENDOR_...TERFACE_INFO(9)

💅 USB_VENDOR_...TERFACE_INFO(9) 💅

okay bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, this is our bonding era ✨ the page title got truncated all cutely as USB_VENDOR_...TERFACE_INFO(9) so that's the vibe we're going with, no cap 💖

---

🌸 NAME 🌸

USB_VENDOR_AND_INTERFACE_INFO — the macro that describes a specific usb vendor paired with a class of usb interfaces 🫶 like, one (1) vendor, whole class energy.

---

✨ SYNOPSIS ✨

USB_VENDOR_AND_INTERFACE_INFO (vend , cl , sc , pr );

literally just four little arguments, she's low maintenance fr fr 🎀

---

🎀 ARGUMENTS 🎀

• vend — the 16 bit USB Vendor ID 👑 (sixteen bits, not fifteen, not seventeen, we're precise here)
• cl — the bInterfaceClass value 💜
• sc — the bInterfaceSubClass value 🦋
• pr — the bInterfaceProtocol value 🌸

---

💀 DESCRIPTION 💀

so this macro's whole job? it creates a struct usb_device_id that matches a specific vendor with a specific class of interfaces. that's it, that's the gig, and she does it flawlessly 💅

and the part where it really eats? this is especially useful when explicitly matching devices that have vendor specific bDeviceClass values, but standards-compliant interfaces. like, the device is doing its own chaotic vendor thing at the top level 🙈 but the interfaces underneath are perfectly standards-compliant citizens — iconic behavior, and this macro is how you match it. periodt 🔥
