Hello there

Love music and as a hoop by for the last forty-five years I have built audio gear. I build everything and in three complete systems in the house they are all 90%+ DIY. which lead me to the Pi2B which I have setup as a music server running Volumio. I chose this OS because it supported the hiBerry DAC+ where the other wanted some coding. I set mine up without keyboard, mouse or screen.

But I can only access one USB stick. In Musicbox all USB sticks inserted appeared but not in Volumio. Can some one tell me how to be able to browse multiple USB drives? Thanks.
