es58x_read_bulk_callback(9)

🌸 es58x_read_bulk_callback 💅

okay so this is a page from the Kernel API Manual, and bestie, it's about one little callback that keeps the ES58X party going 🎉

✨ NAME ✨

es58x_read_bulk_callback — literally the callback for reading data from the device 🫶

🦋 SYNOPSIS 🦋

void es58x_read_bulk_callback (struct urb *urb );

🎀 ARGUMENTS 🎀

• urb — the last urb buffer that got received. that's the whole vibe check, she's the star of the show ✨

💖 DESCRIPTION 💖

okay so picture this: every single time an URB comes in from the ES58X device, this function eventually gets called. not immediately, not on your schedule, eventually — she shows up when she shows up 💅

and what does she do while she's there? three things, in order, no cap:

1. Checks the urb status 👀
2. Calls the read function 📖
3. Resubmits the urb read operation 🔁

that last one is the icon behaviour honestly — she finishes her little task and immediately re-queues herself so the reading never stops. main character energy fr fr 🌈
