USB MIDI keyboard not detected (class-compliant) – Sunset SK-928 / generic MIDI controller

[Faved912]

Hi everyone,
After a fresh install of the latest AtlasOS (Windows 11 24H2), my 88-key USB MIDI controller (Sunset SK-928 – fully class-compliant) is not being detected at all.
What happens:

Using a known-good data cable (printer cable) → works perfectly on stock Windows and other PCs.
On AtlasOS: either “Unknown USB Device (Device Descriptor Request Failed)” or absolutely nothing shows up.
Device Manager shows no “USB MIDI Device”, no MIDI ports, nothing under Sound/Video/Game controllers related to MIDI.

I understand Atlas removes several USB Audio/MIDI drivers and components to reduce latency/services.
Is there an official/clean way to restore only the Microsoft USB MIDI class-compliant driver without breaking the rest of the optimizations?
Already tried:

Different cables and USB ports (rear 2.0 ports)
Uninstall device + reboot
Atlas Tweaker (current version) – no visible MIDI/USB Audio option

Does anyone have a working .reg, .bat, or component package to re-enable the generic Microsoft MIDI driver?
Thank you so much in advance!

You may try it on another PC and then copy the driver from that PC to yours.
There is a driver export tool in Windows:
