okay so bestie, welcome to the Kernel API Manual ✨ — today we're looking at struct dwc2_hs_transfer_time, and honestly it's giving tiny-but-mighty. It's just here to hold info about a transfer on the high speed bus. That's it. That's the whole vibe. 🎀

✨ NAME ✨

 };

• start_schedule_us — the start time on the main bus schedule, periodt. ⏰ but bestie, listen: the main bus schedule is tightly packed, so you have to read this time as tightly packed too. Which means uFrame 0 starts at 0 us and uFrame 1 starts at 100 us — not 125 us. yes this is a jump-scare, no cap. write it down. 📝
• duration_us — how long this transfer goes. that's the whole thing, she's simple like that 🦋

ngl the 100 us vs 125 us thing is the main character of this whole page. if you take one thing with you, take that one. 🙈
