Quartet powers on/off when connected to a powered USB Hub or laptop

Symptom:

If Quartet is connected to a powered USB device such as a USB Hub but not connected to a host Computer, the unit will briefly power on, search for a Computer, then power off if no Computer is found.

Similarly, if Quartet is connected to a powered down or sleeping computer, the same occurs.

Solution:

This is the expected behavior for when Quartet is unable to successfully establish a link with a host computer. Please connect Quartet directly to a USB port on the computer, or use a different USB hub.
