no continuity after computer sleep
I bought this item on amazon. After the computer sleeps - my devices which are plugged into this hub do not register - ie mouse & keyboard. If i unplug/replug the cables they will *usually* come back. If i un/replug the hub-to-computer line i may lose one device and get back another. Its a real mess and renders the thing an irritating little box. I had a similar problem 2 years ago with the same brand and i suppose im a glutton for punishment - i figured the problem could not possibly have migrated to a newer version of this device. Its crap - avoid!

Compatibiliy and Reliability problems
The upper limit on my D-Link 7-port hub seems to be four devices regardless of whether they are self powered. Some devices don't work properly in one port, but do in another, even if they are the only devices plugged into the hub. Furthermore, some devices seem to collide through the hub. For example, only two of my USB drives will run concurrently. Worse, I've seen data corruption when a drive is plugged into four of the seven ports; I thought a La Cie USB hard drive was defective until I plugged it directly into the PC. The center three ports seem to blank out occasionally, but recover after a reboot.
I'm on Amazon now looking for a more reliable replacement. My experience with D-Link products has been more miss than hit.
One final nit is the power connector jack is a right angle type and is a bit loose. I had to improvise a strain relief with tape.

Rumors are true: Does not properly power devices
This hub does not power devices when the my computer is off or in sleep mode. As a matter of fact, if I leave my phone (a BlackBerry Storm) plugged into the hub, and walk away for an extended period of time, the battery on my phone will be drained as a result of being connected to the hub while the computer went into sleep mode. This is a deal-breaker for me, and I will be replacing it with a different hub.
So although I feel misled by the specs, I'll give it at least two stars, since it does function well as a non-powered hub.

power per USB slot
Basically a good product I would have like more juice per channel to power USB 2.5 inch external drives for lap tops.
