Hey there,
yes, this is possible as of version 5.x.x, check out version 5.1.x!
From the Aeros Manual:
USB access to Internal Memory
You can access the internal memory of the Aeros on your computer through the USB port, making backing up your songs an easy process.
To access the internal memory: With the Aeros powered OFF, connect it to your computer via USB and then power the Aeros ON.
Do not connect the Aeros while powered ON or the memory will not be accessed until it is rebooted
To access the SD card, insert it in the SD card slot before turning the Aeros on while it is connected to your computer via USB.
Thanks for the question!
