This. "one port for the pi , two for the sticks and one for a usb DAC "
You are powering the Pi from an unpowered hub ?
Far too many devices for the Pi USB supply.
May all work off-peak but when draw exceeds supply you have problems.
Try a powered hub.
Power the Pi from a proper supply then add a powered hub to the Pi USB out and add the other devices to the powered hub.
