What is the recommended time to connect usb-devices (before rune/raspi is powered or when it´s already running)?
There is no simple answer to this. Depends on the device. I leave USB WiFi and wireless kbd and remote dongles connected, and only connect/disconnect them with power off.
I connect flash drives any time, and RuneAudio has no issues with it.
My own 2.5" native usb 1TB Western Digital rotating HD has to be connected before power is turned on, and has to spin up during the normal Pi USB management sequence to be consistently recognized, but this is not universally the case. A WD "Pi" drive has a different startup, for example, and so does a typical portable USB HD.
If you have a 3.5" HDD as you posted above, your startup will be different from all of the ones I mentioned.

I only get a popup with a check mark on the left, and the text "USB storage connected" or "...disconnected". No tiny icons.
Which RuneAudio image do you have?
