No more USB A power? (Minifuse -> Keylab)

Until recently, I had my Keylab 61 MK3 powered by the Minifuse 4 via one of the USB A ports.
Keylab connected via MIDI Din to MiniFreak and Ableton Move.

Ran flawlessly until recently (might be related to the recent Minifuse update?), but now I have to power the Keylab with an additional power supply to get it working.

When I use my iPad with GarageBand instead of Move (USB C from iPad to USB C Minifuse), the Keylab still works without external power, just powered by Minifuses‘ USB A port.

What’s wrong?
