No power via usb (RPi 3)

I'm trying to get SamplerBox to work on a RPi 3B+.
Have tried to flash the SD card using the ISO on the web site, both via the RPi imager and balenaEtcher. The status lights on the RPi blinks which I assume mean that the Rpi is booting. But when connecting either an Arturia Beatstep or a mouse (just for troubleshooting) nothing happens. To me it seems that the USB ports ain't providing power.

Tried to install the regular RPi system on the card instead and then the Beatstep comes to life without problem.

You more experienced guys, any ideas what I might be doing wrong?
