zd_usb_tx(9)

💖 NAME 💖

okay bestie, listen up — this is the zd_usb_tx page from the Kernel API Manual (yes, that's the manual name, we're fancy now 💅), and it's literally just about one thing: zd_usb_tx initiates transfer of a frame of the device ✨

---

✨ SYNOPSIS ✨

int zd_usb_tx (struct zd_usb *usb , struct sk_buff *skb );

that's the whole signature, no notes, iconic 🎀

---

🎀 ARGUMENTS 🎀

• usb — the zd1211rw-private USB structure 💜 like, this is the driver's own special lil USB thing, not some generic one
• skb — a struct sk_buff pointer 🦋 your classic kernel socket buffer, nothing sketchy here

---

🦋 DESCRIPTION 🦋

so what does it actually do? zd_usb_tx transmits a frame to the device 🔥 simple as that.

but here's the part you cannot skip, bestie — it doesn't wait for completion 🙈 like, it kicks the transfer off and then just... leaves. main character energy fr fr.

also, and this is lowkey important: the frame must contain the control set, and it has to have all the control set information available. no control set, no vibes, no transfer. periodt 🫶

the function returns 0 if the transfer has been successfully initiated ✅ (initiated, not finished — remember, it's not waiting around 💀)

ngl this one's a "fire and forget" situation, so don't go expecting a completion status back. it either starts the transfer or it doesn't.
