STRUCT USBIP_HEADER_CMD_SUBMIT(9)

✨ struct usbip_header_cmd_submit — USBIP_CMD_SUBMIT packet header ✨

okay so this is the usbip_header_cmd_submit page from the Kernel API Manual, and bestie, it's literally the packet header that rides along with a USBIP_CMD_SUBMIT. she's small, she's structured, she's kind of iconic tbh 🎀

💜 NAME 💜

struct usbip_header_cmd_submit — the USBIP_CMD_SUBMIT packet header 🦋

---

🌸 SYNOPSIS 🌸

struct usbip_header_cmd_submit {
    __u32 transfer_flags;
    __s32 transfer_buffer_length;
    __s32 start_frame;
    __s32 number_of_packets;
    __s32 interval;
    unsigned char setup[8];
 };

like, look at her. six fields. no notes. 💅

So each of these fields is doing her own little job, and honestly? teamwork. 🫶

• transfer_flags — __u32, and it holds the URB flags. that's it, that's the vibe check. ✨
• transfer_buffer_length — __s32, and it's the data size for (in) or (out) transfer. yes, both directions, she's flexible. 💖
• start_frame — __s32, initial frame for isochronous or interrupt transfers. the starting point, the main character moment. 👑
• number_of_packets — __s32, number of isochronous packets. counting them like a responsible queen. 🔥
• interval — __s32, maximum time for the request on the server-side host controller. emphasis on server-side bestie, don't forget. 😭
• setup — unsigned char [8] — literally eight whole bytes — and it carries the setup data for a control request. small array, big responsibility. 🌈

🦋 SEE ALSO 🦋

go read the kernel file ./drivers/usb/usbip/usbip_common.h for the whole lore, and then these sibling structs because family:

• struct usbip_header_basic(9)
• struct usbip_header_ret_submit(9)
• struct usbip_header_cmd_unlink(9)
• struct usbip_header_ret_unlink(9)
• struct usbip_header(9)

ok so this page lives under ./drivers/usb/usbip and it's dated October 2026 — that's the source path and the date, both present and accounted for, periodt 💅✨

stay hydrated, read your headers, and remember: the setup array is exactly 8 bytes and that is not negotiable 💖🎀🦋🌸⭐🔥👑
