⭐ UHIDEV(4) ⭐ β€” the uhidev girlies' era πŸ’…

okay bestie, so this is uhidev from the Kernel Interfaces Manual β€” aka the USB Human Interface Device support page πŸŽ€ pull up a chair, this one's short and sweet fr fr.


✨ SYNOPSIS ✨

uhidev* at uhub?
ucycom* at uhidev? reportid ?
uhid*   at uhidev? reportid ?
ukbd*   at uhidev? reportid ?
ums*    at uhidev? reportid ?
uts*    at uhidev? reportid ?

that's the whole vibe right there β€” five little drivers hanging off uhidev with a reportid ?, all of them attached at uhub?. slay πŸ’–


🌸 DESCRIPTION 🌸

so the uhidev driver handles all Human Interface Devices. like, all of them. she's the main character and everyone else is a side plot πŸ‘‘

here's the tea though: each HID device can have several components β€” for example a keyboard and a mouse living in the same device πŸ–±οΈβŒ¨οΈ the way they keep it all straight is by using different report identifiers (a byte) to distinguish which one the data is coming from πŸ¦‹ lowkey iconic.

and the uhidev driver has other drivers attached to it that handle particular kinds of devices, so uhidev itself only dispatches data to them based on the report id. she's not doing the work, she's directing traffic β€” manager energy fr fr πŸ’…

go read those if you wanna know what each one actually does with the data, iykyk 🫢


πŸŽ€ HISTORY πŸŽ€

The uhidev driver appeared in NetBSD 1.6 β€” yes she's been around a minute, a legend honestly ✨


πŸ’€ real talk though bestie: if you're on a modern machine and a keyboard or mouse isn't behaving, this is the driver tree you're crying about. no cap.

made with love, shipped from Debian, dated September 6, 2017 β€” that's the source, version and date up top and down bottom, and no we're not retyping the whole header line, you already saw it πŸ’œ
