Saw this on reddit, super cool. Starred, will play with it later. Great work.

Awesome stuff, thank you!

Even with AI's help, this is still ultimately a solo effort unlike commercial xHCI drivers which have plenty more resources dedicated to development and testing.

I have only tested on 2x Intel laptops so far. So bugs may not be unexpected.

Seems that this project is LLM Assisted. Just need to make that clear according to the forum rules.

That said, this is a great new development and I'm excited to try it out on my ThinkCenter with only USB 3 ports to see how it works.

Understood. I missed that rule out. I should have mentioned in my first post.

My blog post and Github repo readme disclosed that too.

I tested my laptop with a Core Gen 8 (xHCI controller only) – it works (the mouse and flash drive checked).

So, based on the 2025-2026 season, I'm calling this period the Year of Plenty for Windows 9x! 😀

We now have drivers for NVMe, HD Audio, and xHCI (in varying states of readiness, but they're finally here), plus a bonus – second version of the VESA video driver and OPL3 emulator. And this is 30 years after the series' debut! But the most surprising thing is that new developers have emerged, before this Year all was sad.
By the way, we've almost managed to get Windows XP for the supported hardware; it was always, at least slightly, ahead.

And the last but not least - @yeokm1, congratulations! And wishes, of course - don't stop here, try to make driver more universal and do the Super-Speed support.

Hi Sweetlow. Thanks for your kind words!

For more hardware support, I got requests to check on modern AMD systems as that is the next most hardware class for this after Intel. I will see what can be done as currently my sole AMD system, my modern AM5 desktop is tied up.

As for Super-speed support, I would want to also especially for mass-storage. I have some premliminary ideas about how this can be done without having to rewrite the entire USB HCD which will be a significant time-consuming effort even with AI assistance. I will have to investigate more in my free time but I can't promise anything yet.
