pxa_ep_disable(9)

🎀 pxa_ep_disable 🎀

okay so bestie, this is pxa_ep_disable(9) from the Kernel API Manual — we’re disabling a USB endpoint today and the vibe is very “clean up your side of the group chat” ✨. No physical endpoint config changes are happening here, just so we’re clear. Let’s get into it 💅

✨ NAME ✨

pxa_ep_disable — disable usb endpoint 🫶

🦋 SYNOPSIS 🦋

int pxa_ep_disable (struct usb_ep *_ep );

🌸 ARGUMENTS 🌸

• _ep — the usb endpoint, aka the thing being disabled. main character energy only 💅

🎀 DESCRIPTION 🎀

Same as for pxa_ep_enable, no physical endpoint configuration can be changed. The function flushes the endpoint and related requests.

So basically: it’s giving “flush the endpoint and its related requests,” not “rewrite the whole physical endpoint setup.” No cap. 💖
