Query: Won't stay connected to devices

I purchased this product based on all of the great reviews. I love the compactness and the ability to have 7 devices instead of just the typical 4.However, the hub simply won't stay connected to my USB devices. After a few minutes of working, anything connected to the hub will lose it's connection.Hopefully this is simply a single, bad unit. I will return it to the company for repair and will update this review once I hear back.
